If I ever bought a BMW, it would have to be a 540 i......or an M5.
Nice car, but I don't think it will be any less complicated or cheaper to repair than an M-B.
Toured the facory where they are made, 4 years ago. My nephew arranged it, since he is an engineer there.
Sure had a lot of fun driving his 540 on the Autobahn, until a trio of his buddy engineers blew by me at @ 280 km'h.
