We bought the wife's Traverse with the Costco program and it worked out great, one of the best auto buying experiences ever. The person we met with opened a book with Costco pricing, found the Traverse, and said, "Costco pricing on Traverses is $700 below dealer invoice". I had the dealer cost figures in my pocket so I new the guy was not BS'n. Chevy had a $1,000 rebate at the time so we got it for $1700 below dealer invoice. Sales guy showed me the dealer hold back amount on the car and said the dealership still made about $700 on the deal.
