Similar, though in SoCal there are a lot so we've certainly never gotten 6 comments in a weekend.
I think the reason is that when in a regular color it's not flash but there's something undeniably good-looking an muscular in the design. The flares, lip spoiler, f&r bumpers, hood, wing mirrors, roof, lowering, wide tires and widened track all add up to make it look different enough to look special but not different enough to shout "look at me." That brings a lot of goodwill from people who have a passing interest in cars.
The raft of changes ensures I've always stared at M3s with an interest that an M6 with it's regular body could never generate, or a C63 which has changes that look too pep-boys tacked on for my taste (still a nice car, so no offense intended).
While most would say Astons, to me the only other cars I think are better looking are the E46 M3 and perhaps the B7 Audi RS4 (so as you can see, my subjective opinion on car styling is fairly unique)
