1999 106 GTi
Time owned: 3ish years, done 70k+miles though
Problems: Lots - On my 3rd ABS pump as of today, new rear axle today, done rear trailing arms bearings, mid section exhaust, clutch x3 (due to faulty clutches), clutch cable, heater matrix (dash out, git of a job), had a continually leaky power steering pump, alarm box problems, random airbag lights (no major problem, its always the sensor cable under the seat), passenger side door has dropped twice now (gets used a lot), indicator stalk is slightly faulty and makes relay click (annoying!), used to randomly cut out but has improved over the 3 years and never does it now?, random suspension related clunks & knocks and probably others I cant remember.
It'll be back on the road on Monday, after being off for about 2 months

financially a nightmare, its probably not worth the money ive spent on it but the girlfriend loves it and its good fun to drive. The problems ive had have never actually left me stranded or let me down while im away from home. Fortunatly the clutch cable snapped about 2 mins from home, unfortunatly it was a horrible job replacing it due to the invisible hole being behind the steering rack. Clutch being done 3 times was a bit of pain, due to a faulty batch of clutches.
Ive owned the Rover a month or two now, and bar not starting once due to having the bonnet open in the rain, its been pretty solid as a temp car, infact its not let me down at all.
edit: Rear calipers are knackered on the pug too (just replaced them today), replaced the rear ABS sensors today too, my pockets feel somewhat lighter now than they did at the start of the week. Im sure theres more, just cant remember what, ive got a thermostat ready to be put on as im sure mines knackered.
