Love it or hate it, the Bangle Butt (E63) BMW 6-Series is getting cheap.
Personally, I like it. When it first came out, I thought it was a hideous pig and couldn’t believe a styling giant like BMW would ever produce such an ugly car. However, over the years, I have grown to like it. Either way, it is most definitely a styling conversation piece and a unique site.
I hadn’t realized how cheap they are getting though. $10k buys a good one, $16k buys a really really nice one. M6's are still $27k and up, but the V8 powered 645i is still quick enough.
