GM Announces $1000 Owner Loyalty Discount on all Remaining 2007 Corvettes.

GM extends its $3000 red tag discount on all remaining 2007 Corvettes. Now, GM will give you another $1000 owner loyalty discount on 2007 Corvettes if you currently own any 1999 or newer GM vehicle. The program extends to all 2007 Corvettes including, for the first time, the Z06. Is this $4000 discount worth it to you to buy a 2007 Corvette, or is the LS3 worth fore-going the discount for the new motor. What are your thoughts and comments?
