I think juddz has a point. I hammer the dealer and any consumer agencies I could find in your area.
Cobra 953 - I had a problem with a '79 Corvette bought new. The car stalled out when cold whenever you turned a corner. The dealer had it at least a week out of every month I owned it. In August (delivered in March after a 16 week wait) I got mad enough to walk into the dealership and toss the keys on the sales manger's desk. He was nasty so I decided to call Detroit. I got one of their VP's on the phone, I was amazed. Within 10 minutes of my call the dealership called me back, gave me a car to drive while they figured it out. If it wasn't fixed in a week I got my money back or a trade in for what I paid for the car. It was a float in the carb.
Firebase D - sorry about your problems but juddz is right they didn't happen on the manufacturing end of things. That said it doesn't make it not a problem. I lean on the dealer or any other DC reps I could get a hold of.
