" The dealership did offer to have me come back and do a comparison drive with one of their Quads but again, that's 130 miles away and I'm not keen on putting miles and miles on my car for willy nilly tests"
I guess I would offer, as an engineer, that the test would not be "willy nilly" but a straight driving experience comparison of what is being offered these days now and what you have. That is the best non-science test you could be given, to see just how the new car feels compared to what you have, other than actual recorded times, etc. I do think that the feel one gets when driving such an enthusiast car is pretty subjective after a few miles, in that like buying tv sets, the differences in picture quality fade with time. Yeah, there may be a slight difference in times, etc, but the differences in performance of the car ends up relatively undetectable with time.
The dealership IS offering to let you do the comparison, as they should. You could give them that.
Is there a possibility that they have to tune all of the new cars similar to what you have now? That the factory was "over-reaching" in what they were actually selling to the public in the beginning?
Still, I can understand being peeved. I've run across very duff dealers in different parts of the country, most of them back east compared to those out west, for some reason. I never figured out the reason, but I can say, I've also dealt with some very good dealers who listened and accommodated my wishes when they could.
