Go for a used Fiat 500C with the 1.2 or 1.4 petrol and a manual gearbox; the TwinAir has known timing chain, oil cooler and flywheel failures, and the 1.3 MultiJet diesel dilutes its oil.
13 known faults, 4 rated high severity in our database; owners report 48.3 mpg, 82% of the official figure. Everything below is built from that data and the archived owner history, not from a press car.

Check a Fiat 500C advert (free) →A 1.2 or 1.4 petrol with a manual gearbox is the 500C to pick, since neither engine carries a High-rated known fault. The 500C is the 500 with an opening roof, so it shares that car's mechanical faults, and the soft top and boot lid bring a few checks of their own.
Skip the 0.9 TwinAir. Between 2010 and 2018 its timing chain has failed early, often after the oil ran low, and from 2011 to 2017 the oil cooler can start leaking and drain the engine quickly. The six-speed manual TwinAir 105 adds a dual mass flywheel that has given up between 25,000 and 50,000 miles, particularly on cars that have towed.
Avoid the 1.3 MultiJet diesel too. On cars from 2008 to 2017 it struggles to clear its particulate filter on short trips, so fuel ends up thinning the oil and pushing the dipstick level up; left alone, the engine can run away on its own oil. Whichever engine you choose, pass on the Dualogic automated manual.
Little on record covers 500Cs built after 2018, and that isn't the same as them being trouble-free. The same engine and gearbox choices hold for a later car, and so do the roof and boot checks, so judge one on its paperwork and what you find at the viewing.
The 1.2 and 1.4 petrols are the safe choices. The 1.2's cambelt is due every 72,000 miles or five years, and the Euro 5 and Euro 6 versions bend their valves if it snaps. On the 1.4, alternators have failed between 18,000 and 50,000 miles, sometimes more than once on the same car, so make sure the battery light stays off.
The TwinAir is the engine to avoid. It has a timing chain with no set replacement interval, and its main weak spot is the electro-hydraulic valve actuator, which suffers when oil changes are missed; a clogged filter inside it can leave the engine misfiring on one cylinder at around 35,000 miles. Add the chain failures from low oil, the leaking oil cooler and the 105 manual's flywheel, and it's too big a gamble.
The 1.3 MultiJet diesel's filter trouble can show anywhere from 14,000 to 100,000 miles and is worst on town cars. For gearboxes, take a manual over the Dualogic, whose hydraulic actuator cracks and leaks and whose pump fails between 17,000 and 55,000 miles. Manuals aren't faultless: some gearboxes have failed between 27,000 and 66,000 miles, and cars from 2014 to 2018 have lost their clutch pressure plate between 10,000 and 20,000 miles.
Run the folding roof through its full travel several times, since one 500C's mechanism jammed when the car was four years old, and look the rear window over, because on one Abarth 500C a broken one meant a whole new roof. Then try everything electrical at the back: the boot lid wiring loom failed on a 2010 500C.
On the drive, feel for judder or vibration through the clutch pedal and listen for a rattle from a cold start on a TwinAir, the signs of a tired flywheel or chain. Gears should go in without grinding or whining, the clutch shouldn't slip or bite high, and the steering should stay assisted throughout: one 500C's power steering failed at 20 months old. On a Dualogic, watch for a gearbox light or a drop into neutral.
Every warning light should go out once the engine's running, the airbag light included, as the airbag control unit has failed on cars built between 2008 and 2015. The instrument cluster on 2014 to 2017 cars can lose its display or keep warning lights lit. One 2012 500C's passenger airbag half inflated and lifted the dash cover, so check the dash top sits flat.
Ask for invoices that name the oil used and show when it was changed, and pull the dipstick yourself: a MultiJet reading above maximum means fuel in the oil. On a 1.2, ask for proof the cambelt's been done at 72,000 miles or five years. If the windscreen's been replaced, it should be 500C glass with the radio aerial built in, not a 500 hatchback screen without one.

Yes, as long as it's a 1.2 or 1.4 petrol, because those are the two Mk1 engines without a High-rated fault against them. Every 500C also gets the revised suspension shared with the Abarth 500, which gives it noticeably tidier handling than the standard 500 had, so it isn't just a hatchback with the roof cut open.
The TwinAir cars are the ones that go badly wrong: timing chains between 20,000 and 80,000 miles, oil coolers between 30,000 and 70,000, and on the 105 manual the flywheel between 25,000 and 50,000. One 500C TwinAir needed its clutch hydraulics sorting again and again before 4,500 miles. The MultiJet's oil dilution can surface from 14,000 to 100,000 miles, mostly on cars kept in town.
The roof is what sets the 500C apart, and it's where its own problems sit. One car's mechanism jammed at four years old, a broken rear window on an Abarth 500C meant a complete replacement roof, and the boot lid loom failed on a 2010 car; on the 500C it isn't routed through the rubber tube the hatchback uses. A replacement windscreen has to be the 500C type with the aerial in the glass.
