Yep, BMW has pushed their inline 6's as far as the can go (reliably speaking for the domestic market).
The V8 was the most logical choice with all the new high powered/re-engineered opposition from Audi, Cadillac, Porsche, Jaguar, Mercedes Benz alike.
I love the sound of that motor, but the super angular body is just not "cutting" it for me. The 2000 M5 was my most favorite BMW street car to date. It just looked aggressive with its stance (fender buldges, hood, front and rear bumpers...not to mention in a fat 4 door package).
Reference picture:
(I remember the first time I saw the 2000 E39 M5 at the Memphis auto show. I about pooped in my pants. I have a poster of it still. Its a car I told myself I will find and buy when I am 40 and in a mid-life crisis...It was the first car I ever recognized the "deep dish" wheels on. The stance of that M5 in person is just phenominal. Pictures dont do those justice at all)
Its probably a really nice car. But I would take a used high end exotic sports car for the same price anyday over the new BMW's. They are just too TECHY.
