Yes, the GM plan does apply to Caddy's not the new 06 Vett.
I paid 33,850. Car was for around 40K on the sticker. My old car had very good resale value, I put nothing down got my payment for 450.00 leased this time and took home 2 grand cash. Unlike some people I made money on my trade!
I thought about buying, but really I only keep a car for 3 years. Since most of my money is going towards my current project car for track days and autocrossing.
