A hands-on inspection guide. What to look at, listen for, and ask about when you go to view a used Fiat 500 — whether from a dealer or private seller.
Search Our Stock ❯At Fiat 500 Frenzy, we're Sheffield's only dealership dedicated exclusively to the Fiat 500. With over 60 years of combined motor trade experience, Tom and Shane have the expertise to guide you through every aspect of Fiat 500 ownership. Whether you're buying, selling, or just researching, we're here to help — no pressure, just honest advice from people who genuinely love these cars.
Before stepping foot on a forecourt or private driveway, request the complete MOT history online through the DVSA website (free, instant, requires only the registration plate). Look for pattern: passing MOTs with zero advisories suggests neglect or potentially clocked mileage; some minor advisories are normal. Handbrake issues, suspension play, and tyre tread warnings are common and fixable. Significant advisories (emissions failures, brake defects) indicate deeper problems. Request the service history in writing and demand to see original Fiat service records or equivalent stamps from a reputable independent. Gaps exceeding 12 months or 10,000 miles between services are red flags suggesting the car was neglected. Check the V5C registration document to confirm the seller is the registered keeper (or close in ownership timeline—rapid changes suggest previous damage/problems). Verify the mileage on the V5 matches the current MOT and speedo.
Before moving, walk around the stationary car. Check that all four tyres are legally safe (1.6mm minimum tread depth, inspectable with a 20p coin: insert it into the tread; if the inner band of the coin is visible, tread is below legal limit). Look for uneven wear—inner or outer edge worn more than the centre suggests suspension geometry problems or incorrect pressures, typically requiring realignment (£60-150). Note the condition: a car sitting on muddy forecourt or unwashed after months suggests lack of dealer pride or attempts to hide poor condition under grime. Examine the bodywork panel-by-panel in bright sunlight. Check for orange-peel texture in the paint (cheap resprays), overspray on trim pieces (indicates accident repair), and mismatched panel shades (lights, bumpers, doors). Look for stone chips (normal on fronts), but deep scratches through primer or undercoat suggest accident or poor repair. Examine the sills and lower body—classic 500 rust spots. Run your finger along the bottom of the doors and over the sills; if you catch rust flakes, the corrosion is active. Peer at wheel-arch interiors; surface rust is normal, but deep pitting suggests long-term damp exposure. Check for water staining or dampness in the wheel arches by looking up from underneath.
Sit in the driver's seat and adjust it fully forward and back; check for smooth movement and locking in place. Test the steering wheel tilt and reach adjustment (if equipped). Switch on the ignition without starting and check that all warning lights illuminate properly (green/amber lights for electrical systems, then extinguish after 2-3 seconds). A remaining warning light indicates an active fault. Test all electrics: windows (should move smoothly in both directions with no grinding), door locks (central locking on all doors plus remote), sunroof or large panoramic roof if equipped (should open/close without binding). Check the air-conditioning: set it to cold and feel the vents. Proper AC blows noticeably cold within 30 seconds; weak or warm air suggests refrigerant loss (£150-250 to recharge) or compressor failure (£800-1,500). Smell the air output; stale or musty odours indicate mould in the cabin air filter or evaporator (normal in damp climates, solvable with filter replacement and fungicide treatment, £50-150). Test the heater; it should blow warm within a minute and reach hot within 3-4 minutes. Examine the seats for tears, burns, or excessive wear. A car with 80,000 miles should show some wear in the driver's seat bolster; pristine condition suggests clocking. Press hard on the seat base and back; if it flexes excessively or foam is compressing unevenly, the seat has been heavily used or sat in by heavy people (not a concern mechanically, but reveals true wear). Check the steering wheel and gear knob for shine (worn to bare plastic suggests high mileage despite what the speedo says). Examine the dashboard for cracks, air-vent staining (indicating previous interior water ingress), and any broken switches or trim. Test the infotainment system: enter the menu settings and check how the mileage logs (should match the displayed odometer and MOT records). On post-2015 models with touchscreen Uconnect, verify it responds to touches without lag, check that the reversing camera (if equipped) displays clearly, and test connectivity (Bluetooth pairing, Apple CarPlay/Android Auto if equipped).
Open the bonnet and look for evidence of major leaks: oil pooling, coolant staining (usually green or pink), or transmission fluid (red, thin). A small drip is normal on older cars; puddles beneath the car parked overnight indicate a problem. Inspect the oil dipstick: the level should be between minimum and maximum marks. Dark, thick oil suggests infrequent changes or old oil; fresh oil is honey-coloured. Check the coolant expansion bottle (usually transparent plastic); fluid should be visible between min/max lines. If completely empty or overly milky, there's overheating or a coolant leak. Look at the engine oil cap and underneath the cap for white, mayonnaise-like residue—indicates head gasket failure and water in the oil (serious, potentially £1,500-3,000 repair). Examine the battery; if corroded terminals show, poor maintenance is indicated. Look at the spark plugs (accessible on 1.2 and TwinAir, less so on diesel): they should be light tan or grey; sooty black indicates running rich (carburettor issues on old cars, though fuel injection on modern 500s rarely has this), and white/ash colour suggests very clean running or lean condition. Check for obvious leaks around the sump, gearbox bell housing, and transmission pan. Hoses should be supple, not cracked or brittle. Examine the serpentine belt (the long rubber belt driving ancillaries); it should be intact without cracks, glazing (shiny patches), or fray marks. A worn belt costs £40-80 to replace.
Turn the key to start. A healthy engine fires immediately with a smooth crank. Rough starting, extended cranking (more than 3-4 seconds), or multiple attempts to catch suggest worn starter (£200-400), flat battery (£60-150), or fuel system issues. Listen for knock or pinking (metallic tapping increasing with throttle)—indicates low octane fuel, carbon buildup, or timing issues (pre-facelift 1.2s can suffer this). Once running, check the idle: should settle to a smooth 800-1,000 rpm within 10 seconds. TwinAir engines are naturally slightly rougher than the 1.2. Excessive vibration through the steering wheel or foot pedals suggests worn engine mounts (£300-500 to replace all four). Observe the exhaust: black smoke (especially on a warm engine) indicates running too rich; white smoke on cold start can be normal condensation but persistent heavy white smoke suggests coolant burning (head gasket). Blue smoke is oil burning, common on high-mileage TwinAir or 1.2s with worn piston rings, though normal TwinAir consumption is covered by the service history you'll check. Green smoke is extremely rare and suggests solvent ingress or experimental fuels. No visible smoke is ideal.
Always test-drive on varied terrain. Start by noting how the clutch engages (manual cars): should bite smoothly between 25-50% pedal travel without shudder. Abrupt engagement or chatter (vibration through the pedal) suggests a worn release bearing or pressure plate (£500-800 clutch replacement needed). On automatic/CVT cars, shifts should be smooth; any hesitation, jerking, or delayed responses indicate transmission problems. Accelerate moderately up a short hill; the engine should respond linearly without knocking. On TwinAir engines, expect a small turbo lag below 2,000 rpm, then responsive power. Listen for engine noise: a mechanical knock at higher revs suggests bearing wear (serious, engine rebuild required £2,000+). Drive over rough ground and listen carefully: clunking from the front suggests worn top mounts (£400-600 per side) or lower arm ball joints (£200-400 per side). Clunking from the rear indicates worn anti-roll bar bushes (£60-150) or shock absorber mounts (£300-500). Vibration at specific speeds (e.g., 55 mph) suggests unbalanced wheels (£20-40 to rebalance). Brake from 30 mph and feel the pedal: should be firm, not spongy (indicates air in lines or worn pads affecting feel) or fading (repeated hard braking causing repeated fading suggests problematic braking). Listen for squealing (normal wear indicators) or grinding (worn pads; change immediately, £80-150 per axle). Steer through tight corners: the wheel should centre itself after releasing it (power steering assist). If it doesn't, worn steering components or low power steering fluid (£20 for fluid top-up). Try the handbrake: it should hold the car on a gentle slope with moderate pressure. On a steep hill, if it's weak, brake wear or cable stretch may need attention.
A clean engine bay with no evidence of leaks or damage is a sign of proper maintenance.
Manual Gearbox: Shifts should be clean and direct, with no grinding between gears (suggests worn synchromesh, typically on 3rd or 2nd; replacement requires full box removal, expensive). The gear knob should lock into each position without rattling. Reverse should engage with a slight notch feeling. Dualogic Automated Manual: This transmission is the 500's Achilles heel. On the test drive, it should shift decisively without hesitation or shuddering. Any uncertainty (longer-than-normal shifts, shuddering during upshifts, or a "hiccup" downshifting to 1st from 2nd) suggests imminent actuator failure (£800-1,200 to replace). If warning lights appear on the dash during the test, this box is failing. Avoid unless the seller provides a rebuild invoice with warranty. Six-Speed Manual (2015+): Smoother and more reliable than earlier boxes. Engage all gears and listen for any grinding; silent, clean shifts are expected. CVT Automatic (2017+): Should be smooth, with no jerking between load points. Modern CVTs are robust; any hesitation suggests fluid degradation or belt issues (expensive to repair, typically £2,000-3,500).
This matters more than most buyers realise. Look for signs of interior dampness: musty odours (worst indicator), staining on the headliner, or damp carpets beneath the seats. Open the boot and check the spare wheel well; if it's wet or has permanent staining, water has entered and may not be easily drainable. Check behind the rear seat cushion (often removable) for water staining. On cars with panoramic roofs (especially hardtop electric 500s), check the headliner for water stains extending from the roof edges. Test the windows: on a humid day with the car heated, the inside of the windows should remain clear within 5 minutes of stopping. Persistent misting or condensation on the inside of the glass on a warm day suggests a leaking seal or interior moisture (potentially mould). Do not ignore this; mould remediation is difficult and expensive (professional detailing £300-600+).
Have a helper apply steady pressure to each corner of the car while you observe: the suspension should compress evenly and return to ride height without bouncing excessively. Repeated bouncing indicates worn shock absorbers (all four should be replaced together, £500-800 for parts and labour). Uneven compression (one corner barely moving) suggests a seized or totally failed shock. On a tight corner, listen for a pop or creaking sound from the suspension; this indicates dry ball joints or worn bushings (suspension geometry is critical to handling and safety—address these). Check the steering rack by turning the wheel side-to-side while stationary: it should move smoothly without notchiness or play. Excessive play (more than 2 inches of wheel movement without the front wheels turning) suggests worn rack ends or main bearings in the rack (£200-400 for ends, £800-1,200 for a full rack assembly). Electric power steering (EPS) on all modern 500s can fail, leaving the car with manual steering (still drivable but harder). If you hear a noise from the steering column on sharp turns, this is a red flag for EPS issues (repair costs vary, but new units are £1,200-1,800).
Always check the complete MOT history on the DVSA website before viewing a car.
This is non-negotiable. Pay an independent Fiat specialist £100-200 to conduct a full diagnostic scan and inspection. They'll connect an OBD2 scanner to the engine management computer and retrieve any historical fault codes, revealing problems the warning lights might not have triggered yet. They'll perform a compression test (identifies worn rings and valve seats), check transmission fluid condition (dark fluid indicates wear or overheating), and perform a thorough visual inspection from underneath on a ramp. This investment catches hidden transmission failures, electrical gremlins, and structural rust before you commit. Many private sellers and small dealers refuse permission for this inspection; if they do, walk away—they're hiding something.
