A used Alfa Romeo Giulietta is worth buying only with receipts for the cambelt and every oil change; skip a 1.4 MultiAir that misfires, idles roughly or shows an engine warning light.
2 known faults, 2 rated high severity in our database; owners report 42.3 mpg, 79% of the official figure. Everything below is built from that data and the archived owner history, not from a press car.

The 1.4 MultiAir petrol's actuator unit can fail between 40,000 and 80,000 miles, and owners of a 2010 1750 TBi Cloverleaf and a 2010 2.0 JTDM-2 have had timing belts break far earlier than they expected.
That makes the paperwork the deciding factor. On a 1.4 MultiAir, skipped oil changes or the wrong grade of oil are often behind the actuator going, so an unbroken oil record counts for more than the mileage. On a Cloverleaf or a 2.0 JTDM-2, ask for a receipt showing when the cambelt was last changed, and don't accept a verbal assurance in its place.
Cars from the 2010 launch and the facelifted ones from April 2016 get the same advice, since nothing on record says the later cars were changed, so don't assume a newer one's sorted. The 2.0 MultiJet diesel with the TCT gearbox was recalled because that gearbox couldn't be relied on to work properly, so on one of those ask for proof the recall work's been done.
There isn't a Giulietta engine with a clean record, so the lesser risk is whichever one comes with the paperwork for its weak spot. On the 1.4 MultiAir petrol, the actuator unit can fail between 40,000 and 80,000 miles, leaving the engine running on three cylinders with a warning light, a rough idle and little power. Irregular oil changes or the wrong grade of oil are often the cause, so the oil record matters more than the mileage.
On the 1.4 MultiAir, the cambelt's due every 72,000 miles or 60 months, so ask for the receipt if the car's near either. Belts have also broken early on two 2010 cars. One owner's 1750 TBi Cloverleaf lost its belt roughly 55,000 miles in, only three weeks on from a service where they'd been told it could wait until 63,000 miles, and a 2.0 JTDM-2's went only 30,000 miles on from a belt change its owner could prove.
The 2.0 MultiJet diesel with the TCT gearbox was recalled because that gearbox couldn't be relied on to work properly, so get proof the recall work was done. The 2.0 JTDM-2 140 was set up to go 21,000 miles between services, which is a long stretch, so look at how often the oil was actually changed rather than just whether the stamps are there.
Open and shut the tailgate, then try the rear wiper, the reversing light, the boot light and the heated rear screen, because two owners have had the wiring looms at the back of the car fail. On one 2010 car the broken cables left the boot locked shut, and that owner paid £502 for a dealer to repair them. On a 2012 car, the loom for the rear wiper gave up at 89,000 miles.
Ask for receipts for the cambelt and for every oil change, and check the dates and mileages on them match the car. Two 2010 cars, a 1750 TBi Cloverleaf and a 2.0 JTDM-2, have had belts break well before their owners expected, so on either of those engines don't take the seller's word for when the belt was last changed, and see how old the receipt is.
On the drive, a misfire, a rough idle or an engine warning light on a 1.4 MultiAir points at the actuator. Check the stop/start works, since one owner's 2014 1.4 never got it working reliably, and make sure the climate control blows the same temperature on both sides, as one 2011 car lost a flap motor in the ventilation and sent warm air to the driver only.
Try the headlights and indicators, because a faulty stalk pack can make them play up. On a QV with the TCT gearbox, look round the inlet manifold for coolant, as one independently serviced 2014 car leaked there. One owner had to replace the front suspension bushes when the car was only 30 months old, so listen for knocks over bumps too.

A Giulietta 940 is a good buy only when its history covers the weak spot of the engine you're looking at, whatever the year. It earned five stars in its 2010 Euro NCAP crash test, though it was rated at three stars in 2017, and the ride's very firm on cars with sports suspension, so try one on a rough road before you commit.
The 1.4 MultiAir's actuator unit is the fault to plan around, turning up between 40,000 and 80,000 miles as a misfire, a rough idle and a loss of power. On the earliest cars, owners have had belts break far sooner than they expected: a 2010 1750 TBi Cloverleaf at roughly 55,000 miles and a 2010 2.0 JTDM-2 only 30,000 miles on from its last belt change.
Inside, it's cramped and there's plenty of hard plastic, and the 2016 facelift didn't stop it feeling its age. The wiring looms running into the tailgate deserve a close look on any year: one 2010 car ended up with its boot locked shut when the cables broke, and the rear wiper loom on a 2012 car failed at 89,000 miles.
