Best car service for higher end foreign cars is a private shop called Vancouver euro exotic inc. They have the same computer as Ferrari Vancouver and the only other shop that can fully service Ferrari/Maserati vehicles in B.C... Did an amazing quality job on my car and at a decent rate compared to other shop and it wasn't just an oil change. Full clutch change which is considered a really big job,mechanic even took me for a test ride after to show me tips on how to properly drive/shift with F1 which was priceless, blew my mind how smoothly he drove my car as I never had experienced before.
FYI.Seen a mb SLR 766r on the hoist last week there so u know they are well trusted and experienced in quality car care for the extreme higher end car guys and make these dealer shops look like the idiots they think we are. Trust me give them a try and you'll never go dealer for ur highend vehicle again. Hope this helps. Pm any questions
