GoodEnough,
I think you handled that with much grace! That had to be hard to keep your cool. You say the car is perfect now, are you happy with it?
Somebody I know had a pick-up, I think it was one of those small dodge trucks. Turned out that it didn't have the towing capacity that it stated and after they had the truck for a year and 15Kmiles, they got a full refund for it. They weren't even towing anything with it, I guess it was something that Dodge came to them with and they had no idea about it before then. I can't imagine them getting ALL their money back after driving the truck for a whole year like that!
Some people just have all the luck and some don't.
