2009 Corvettes

GM's Open House promotion gives everyone the GM Supplier Discount pricing
If you qualify for the GM Employee Discount (GMS), you are eligible for $500 off
If you have a Nissan or Infinity in the household (2000 or newer), you are eligible for $1,500 off

If the Corvette you're interested in is an "old invoice" unit, or one that has been in a dealer's inventory for a long time, you are entitled to $1,000 off.

There's no way for a consumer to check on those units that qualify, so if you are interested, please contact the selling dealership and inquire about the program.

2009 Corvette ZR1s do not qualify for any of the above programs, except the "Old invoice" program, but most likely none of those would qualify either.
