I own an F10 M5 and echo pretty much everything said above. I really want to get it on track as there is no way you can use even half its ability on the road. AMGs have a real image problem to me which is why I went down this route, but both are great everyday cars. My car was a used 2012 with 9k miles showing, year's warranty, 2 year service pack and very good spec. I paid 41k. I can't think of a better car at any price.
