I went on Friday evening, and no they do not, nor did the DC show. With the DC show moving to the week after Detroit rather than a few weeks prior there were a lot of concept and new release vehicles that were at the DC show this year, but not the '08 Viper. The Baltimore show is part of the Motor Trend series and is not a "major city show" but the ME 4+12 that was debuted at Detriot a couple years ago is at the show and if you have not seen it in person was cool to see. I don't think any of us think it was anything more than a styling excercise....
Last year the local Viper club had several cars on display which is part of what I like about the Baltimore show is that there is a decent display of customized cars as well as club showing....but this year the only club is the Corvette Club of Baltimore County and they didn't even have a member displaying a C6 Z06. You missed your chance to get Will Castros' autograph last night...and the line wasn't very long ;-) I would have been interested in seeing more of their work displayed than just 2 vehhicles one of which was locked up and didn't demonstrate anything more than a set of wheels and some pinstripes.
Overall I'm glad I went, but I'm even happier that I didn't miss the DC show as well as the combination is what worked.
