After 9 years of owning two E39 M5s that were basically trouble free, I bought an e60 M5 and loved the sound of the V10, but after 4 years I always wondered what was going to break next and the VANOS forced me off the shoulder on I95 in Florida. I will always love the V10, but I was lucky enough to find a 2013 F10 with 17,00 miles on it and a BMW 2 year warranty on the powertrain. I love the F10 and I have fallen in love with trouble free miles on my cross countries to visit family. I'm not sure if the driver's seat massage was an option, but I think all M5s should have it. Now starts a new era with the F10 and so far I love it best of any of the M5s I have owned.
