I like deals! My ZR2 had a sticker of $73k, had a tonneau and tint that put it nearly$75k, I paid $67ish. I'd give them $73k for that Bison. I tried to deal with that dealer for my ZR2 and wife's Tahoe. They wanted MSRP +5k. They couldn't understand how I got $5k off Tahoe and $7K off ZR2........I said I just asked and eventually they took the deals......seems simple to me.
My 22 ZR2 was technically 8 months old when I bought it. Somehow got lost in the back lot, or I wouldn't have gotten that price.
