Burkhard is a great guy - no affiliation but know him fairly well. Secondly, Burkhard does NOT work at the Ferrari dealer Ross (10-17 at 3:05) I assume you are looking at a Ferrari he has for sale ? He works at (basically every brand but Ferrari mega-store i.e. Penske) Not the Ferrari/Mas dealer on 68th st/McDowell So if you want to get a PPI done, I feel you can trust them because they are not the dealer.
