RE: new challenger price
I can only hope (can only HOPE...) that Dodge dealers don't do what the Pontiac dealers did when the GTO came out in 04 - they had all sorts of dealer markups, plus they had Fort Knox-style security around them, and forget about test driving one unless you were willing to put a several thousand dollar deposit on it (and they WONDERED why the cars weren't selling...). Finally later on in the year I was able to get one for several thousand off sticker (go figure, eh?).
That's why I'm not even gonna think about a first year 08 model. Late 09 at the earliest, I'll go for a late 09 or an early 010.
