While overall auto sales have recovered somewhat from the depths of early 2009, things are still pretty slow compared to their peaks. General Motors has done a decent job of avoiding too many customer rebates since it emerged from bankruptcy a year ago by controlling inventories. However, that's a lot harder to do with low volume cars like the Corvette and especially the ZR1. Balancing adequate dealer stock and too many cars is tough when the numbers are so modest to begin with.
With the 2010 model year winding down, GM reportedly still has about 500 ZR1s in stock and is now offering $3,000 cash back or zero percent financing on 2010 models. If you look hard, you may even find one of a dozen or so 2009 models left over which will get you $5,000 off the sticker price. Unfortunately the 2009s aren't equipped the very effective and easy-to-use launch control system that became standard on the '10s, but it's still a deal if you can get one.
Update: General Motors spokesman David Caldwell let us know that the incentives are not just for the ZR1. GM simply removed the previous exclusion of the ZR1 so that existing Corvette rebates now apply to the supercharged model.
