First let me say Hello. I am new here so I will try not to step on any toes. Not everyone who buys a car from the group you named pays a premium. I purchased a Z28 from Charlie Sheen and got a great deal. What made the deal for me is that Charlie L. had bid on the car. That held more weight than Charlie Sheen. I kept that paperwork for proof. Maybe if I sell the car it will be sold at a premium because of both Charlies?
