Anyone have anyexperience ordering items form Carter VW in Seattle? Their website says OEM at 10% off or so. No one in New Mexico has a hitch, so I am going to buy one from them and have it installed in Albuquerque. Any advice on who should do the installation? Only the dealership? WIll they need VAG the wiring harness to move it to US specs (based on my search, I take it this has been an issue)? THanks for your help.
