Say it with us now: create demand. Challengers won't roll off the line en masse next year. Instead, as we reported last month, Dodge is going to make just 5,000 of them for the '08 model year, all SRT models with 5.7- or 6.1-liter Hemis. In 2009, Dodge will widen the sluice some, with output expected to be 30,000 to 35,000 cars. That is also when six-speed manual and dual-clutch options could be added. The Challenger will take the stand next year at the New York Auto Show. And for those of you planning to buy a 2008 model, especially one with the 6.1-liter Hemi, say it with us now: residual value.
