Not just for warranty considerations did I buy the mp215, but also for assured long term reliability. That is, I'm not just concerned with not having a problem show up during the first three years, but I don't want one to show up for 15 years or more. I'm planning to hang on to this car and not buy another one. Ever. But then again I'm in the older demographic. .. If I were a youngster, and planning to replace this car if 5 to seven years, my decision may have been different, not only in having the tune done, but in choice of ride to begin with. As a side note, this may be the perfect retirement car! Ive seen way too many people make their final automobile purchase a large luxury car. Then I see them just barely sticking over the steering wheel and puttering down the road afraid to hit anything because the car is so large. At least the seat has height adjustment. :happy:
