Are they a maintenance nightmare or does the high price reflect a better quality than most, or is it all the same as with other vehicles, drive it nice and keep up on the regular maintenance and its good to go for many years? A friend has a nice supercharged 06 rr and offered it to me in the new year possibly. I like the way they ride, nice and quiet inside, heated seats the whole nine yards. Anyone have any experience long term with them? Thanks!!
