I had a few of the so called worst cars available and never had issues with any of them. I've had 2 Alfa's, a Land Rover, 2 Fords and a Jeep. Maybe I'm just lucky but I believe it's how you treat things that counts.
The Jeeps gearbox did pack up at 70,000k's. It gave all the warnings etc (dashboard lights) but the agents in George told me 'it's nothing serious' and that it would be fine to drive to CPT. It wasn't but I can't blame the car for that. I kinda blame myself for trusting the dude at the dealership because he didn't seem very sure of himself but I didn't want to have to leave my car in George for a week while they got the part they needed.
I have a good friend who's BMW has been in the garage for more days than it's been out. I have a colleague who has endless hassles with his VW. Both drive like mad all time. Just my view.
