Yes. yes I do. That said, the friends who desperately wanted me to buy an AMG ("one of us, one of us, one of us") have a commercial shop with lifts up in Lynden and they are itching to demonstrate its mechanical inferiority through maintenance.
I also purchased the vehicle in no small part because it has experienced over $17k in maintenance in the past 18 months, during which time it has driven less than 100 miles (not including the 900 miles the dealership put on the dyno so they could fill its ECM with history for emissions testing). Said dealership actually charged the guy an hour labor to put on the tires, then billed him per tire weight.
I also accidentally downloaded the shop manual to my phone while looking to see if it was available on the Internet.
Finally, I don't drive much. I really don't. For work I ride a bike and when I'm not working, I basically drive to pick up my daughter or run errands. The 1500 miles I put on it last week will likely not be exceeded again through 2019. The car basically exists because I can't pick up my kid on a motorcycle. I'm exactly the guy to take on the care and feeding of a 15-year-old Porsche.
