I am really sorry to highjack the post, but I had to re-read rick's post several times and I am still scratching my head,
Rick, I am not sure what is the problem with your Z06
A window stopped working. OK. Simple warranty fix. The only problem in 2 years - that is not bad all. I know acura owners who take their cars for several warranty repairs a year with problems of a similar scale. Hell, I've seen a 2 month old ferrari getting towed away with a non-starting engine :bang: If you are afraid to go to a dealer for a fix, your problem is with a dealer, not the car. Look around, there are dealerships with competent service people.
There are recalls on C5s. OK. sure. There are also recalls on Toyotas and BMWs. So what.
I am not sure what the "refinement of the engine" means.
MPG-wise C5 is ahead of C4.
Z06 "sits in one spot" compared to Zr1? 405HP and 3200lbs vs 385HP abd 3400+lbs? Does not add up.
you either drive 40mph in 1st gear or they sold you a broken car to begin with.
Unless your car came somehow crippled from the factory, it really sounds like your issue is with your own decision to buy a new car and some dissapointing dealer experiences. I don't think it's fair to blame either one on GM or your car. Just my opinion.
Back on topic:
I drive the Z daily, rain or shine. It is truly "a beater" as far as function goes. I also drive it on the track. And on the few thousand mile roadtrips. It does everything (well, I would not drive it in the snow). It is comfortable to drive on the long trips and gets almost 30mpg on highway.
I have been to the dealership 3 times - swapped headlight actuator, fuel filler hose and windshield fluid sensor. For 3.5 year old car that is being driven and not just waxed once in a while, this is pretty good.
Oh yeah, I got it used at a very reasonable price, so no buyer's remorse here
