The 2011-on car is the best. If only it wasn't so crazy heavy it would be an all-time great. I drove one of these last week and that engine had me eating my words a bit, it is epic.
Being an owner of an E28 and and E34 and having driven all variants except the latest one. Each of the cars are very different having their own personality.
For me though, the E28 will always be the original and best.
