Sure. So am I. I contract hire because I don't have several grand to blow on a car and I think buying one several years old on finance is even dafter than just paying for the depreciation on a new one with a warranty. I've dealt with a LOT of shit in my life, and I assure you, a crappy new car (I've had a couple) has never been sufficient for me to claim that the stress was causing me health problems. I honesly have never heard something so daft in my life.
Eating badly, not taking care of yourself correctly, abuse, personality disorders, abusive behaviour from other people, intense pressure from work and home... I guess these can be valid causes of stress.
A crap car?
No.
