Costco Costco Auto Buying Program. Well I always knew that Costco had a program for buying cars. I didn't realize how online it is. Now you can contact dealers online.

Also if you are an executive member and you go to a participating dealer, you get 15% off of service, parts and accessories. That alone could be worth the $100 membership. I don't know what participating means though. Probably for dealers way too far off the beaten path.
