BMW’s 2012 6-Series Gran Coupe will be the first 6-Series in history to go beyond two doors. To improve rear legroom and fit the additional two doors on, BMW has stretched the wheelbase 4.4 inches beyond the regular 6-Series. The Gran Coupe will be wider, lower, and longer than the 5-Series.
I'm interested in buying one but I don't really know much about it's history & reliability, So I'm looking to for some information from pass owners or just people that know a lot or just enough about it. Between the years of 2004-2006, so the 645 & 650.
