Went to Secret MBZ last week for first time for Schedule B maintence. Louie quoted a price which was a lot lower than the dealer and that is what I paid. During the inspecection, they discovered a few other areas where maintence was overdue (eg, spark plug replacments) and Louie emailed a description of their discoveries and what it entailed and a price quote for each. His explanations were very clear but there was no pressure to do them. What was nice is you could either call or select from the email if you wanted any, all or none of the additional services done. The car is running great and I recommend that you go here and save hundreds of dollars instead of the draler.
