Mostly when something was needed as cheaply and quickly as possible
My Worst have nearly all been fords though:
1993 Mondeo - Turbo Diesel - Slooooooooooow! took an age for the turbo to kick in
1994 Fiesta 1.4 LX - The LX bit is important as it meant comfier seats than normal! - Again slooooow but i was desperate for a car and it only cost me £60 (with mot and tax!)
1991 Escort 1.3 - SLOOOOOW and horrible and crap and crap crap crap crap hated that car but again got me out of a hole and was only £150, 80,000 miles on the clock one owner from new, full service history and T&T
1992 Renault Clio AUTO! - This was definitely the slowest car i have ever driven! It was free as the previous owner had left it in a car park and the car park flooded

Strangely though one of the best cars i had was a Renault Laguna RT MK1 - 1.8 petrol 8v engine. The most comfortable car to drive, the seats were awesome. Lasted me 4 years before i sold it on. Cost £1100, 4 years later sold it for £900 so not bad! Very very good on petrol too, only probs i had were a dickie immobilisor at first (easily sorted) then one of the coil packs died, £35 to replace
