It would be quicker to explain what didn't go wrong! This said, it later came to light that the car had been used by a dealer as a courtesy car - maybe this review reflects the quality of the (now defunct) dealership from which the car was purchased.
Wheel bearings needed replacing after about 2500 miles.
Clutch went after about 5000 miles.
Major rust problems on the sills.
Driver's window fell out!!!
Lots of electrical gremlins.
Eventually the piston rings gave up, the engine burnt ridiculous amounts of oil and the car was sent to the scrapheap.
This car handles like a house brick on an ice rink - the highish centre of gravity coupled with poor suspension results in shock if you try to corner at a speed which would be considered reasonable in any other car.
For a car designed as a "shopping trolley" the boot lip is ridiculously high for loading/unloading.
The tank-like build wrote off a Ford Escort with only bumper damage to the Yugo - however this lack of any crumple zones would be disastrous in a motorway pile-up!
