How about the 5 cars you'd least like to own
Pontiac Aztec,
http://en.wikipedia.org/wiki/Pontiac_Aztek possibly the ugliest car ever made
Volvo 343 Automatic, awful, awful car apart from the heated seats
Ford Scorpio, ugliest car ever sold in the UK
Mk 1 Austin Allegro, apparently if you used the rear jacking points the rear window fell out. Had a square steering wheel too.
Suzuki Vitara, just hate this car and it's image
