Hey guys, this question is a little for me and for one of my friends. I have been possibly looking at the option of an E60 M5 in the next year or so, prices are just too good. Also, finally got one of my friends interested in BMWs again, and he was looking at getting a newer 335i w/Sport package and probably a few other options, and definitely a manual. Seems like a good one will run about 26-30k with half-way decent miles. I told him that if he was looking at that price range, and was also maybe willing to throw a few grand more in, he could be getting into an M5. Now, the one thing is that he's worried about the cost of maintaining an M5 vs. the 335i, and I guess I would be interested in it too. How would the cost of these two compare? Is there a large difference? Other than the occasional SMG issue that seems to pop up, it seems that the M5s are fairly reliable. Is this a fair assumption? Thanks so much for the help.
