Welcome to CHR!

There's a Gateway Showroom near me, and I have a friend that sold a bone stock '46 Chevy there a while back. Shine is right, Gateway is only a consignment house/broker, NOT a car dealer. They take in cars for no consignment fee, do a photo shoot and video clip, then market the car across the country and OUS with 20 showrooms. The initial 7 days the cars are in their on-line auction, and if sold at auction the seller pays a 12% sales commission, with a buyer's premium in addition. After the auction period Gateway markets the car, and if sold the seller gets his set minimum price, and Gateway keeps anything above. They do detailing and marketing, but don't do any kind of inspections to verify quality. Cars are sold as is, where is, no guarantees and they will arrange transportation. Like Shine says, prices are negotiable.
My friend says that if you go to a showroom and they believe you are a serious buyer they will let you drive a car, but only in their parking lot. The consignment agreement says that the car will remain on property at all times. For me, I would not buy without going to see the car in person.
