Anyone deal with or know anything about "Cherner Classics" in the US?

They are finishing CAVs and selling them via ebay and the auto-trader. Wondering if anyone knows anything about them.

Cherner Classics

 

They are about a mile from our house. I bought a Ferrari from them and was pleased with the service. They have a selection of owned and consignment cars. Asking prices are generally high, but they do negotiate. My son saw the GT40 but it is was not there today. They are owned by a local L-M dealer.
