I REALLY want to thank you guys for all your input. As DarcShadow said, the car had been on the track ... a LOT. The dealer that looked at it (NW Dodge in Houston) did a really poor job of checking it out. Even told me that the car showed no evidence of being on the track (even *I* could tell that wasn't the case!) ... they also told me that the valve covers were SUPPOSED to be all red like that.
I didn't even drive it after flying down there and seeing the shape it was in. The sales person (Phil) was very honest with me as we took it out with him behind the wheel. I appreciate his honesty and would recommend going by there just to look at all the cool cars when you're in Houston ... it's a very unusual used car dealer.
A quick summary on what I found. The rear tires had heavy balling, even on the edges of the tread (hard cornering, usually track inspired). Paint chips all the way down the side on the lower part of the body (usually due to hard cornering with other cars in front of you). Air dam on the front had met up with a BUNCH of parking humps ... they didn't even TRY to hide that. Hood was a bit whacky ...not quite square. Driver door sagging about 3/4 inch. Interior nice, but not anywhere near perfect. Shocks were shot! DS mentioned the side pipes ... they were straight pipes with no mufflers at all. It was so loud that one of the customers commented that it sounded like a tractor when it pulled up...impossible to even hear a loud conversation when at anything above a fast idle on the road. Shifter didn't move smoothly through the gates. Overhead storage netting was stretched so far out that it needed to be replaced. Still had an amplifier in the back (probably didn't work), but the speakers had been cut out and wires left exposed.
Overall, not my idea of a good first Viper! Might make someone a nice track car for 10K less money, but otherwise, don't bother with a trip down there.
Again, thanks for the input. We're still looking for a Gen II GTS that has been lovingly cared for. A track day every now and then is fine as long as the owner still loved the car enough to take care of it. If you run across one, let me or DarcShadow know.
