In the Corvette world, there are several high volume dealers with very transparent pricing and fees. They make it very easy to order a car and either pick it up or have it shipped directly to you. I have searched, but I am not seeing options like this in the Mercedes world. When purchasing vehicles, I find myself typically having to leave the local market which is dominated by one of the big mega dealership monopolies. Any purchase advice would be greatly appreciated.
