VW Fox, had one for 3 days as a courtesy car, had 20k on the clock, both doors leaked water in, the passenger door panel was off because the window had been wedged shut due to the mechanism breaking, ignition barrel was wanked so the steering lock wouldn't disengage, shit stereo, seats like a deck chair, no storage space, wouldn't take any corner at any speed.
VW Up! wasn't much better, although guess they are cheap for a reason. The 3cyl lump did a good burnout though lol
