I put approx. 21k miles on my M3 every year.. had it about two years so far. I drive it all the time because I love being in my car, especially after mods. I plan to drive the car until it dies. Also, get as much use out of it as you can, because in a few years, the new one comes out, then another, then another, and the small percentage you lose in residual value, I feel, is negligible. Just my two cents, and as tibra1 said, "To each their own." Just sharing my thoughts
