Thanks! I've been on that one as well. I guess this board doesn't favor M5's.
We love M5s here too, but that is THE place to go for M5 information. Most of those guys have M5s and have been modifying them for years.
In answer to your original question:
The M5 is the epitome of a sports sedan. Indeed, the original M5 created the sports sedan segment way back in 1984, earlier if you count the E12 M535i that made its debut in the late 70s. MB fans would argue the MB 300 SEL 4.5 from the early 1970s was the first sports sedan, but as today, the MB emphasis was on speed, not sport.
The original (E28 chassis) M5 played a strong role in my love of the automobile and of BMW. In 1984 I got a book called The World's Fastest Cars. I was 8 years old (but reading at a college level, so not interested in age-appropriate material). I still have that book. There was no M5 in that book, but there was an M6 and an M535i (along with a few 7s and an Alpina C3). At the tender age of 8, I thought to myself that it would be great to put the S38 Motorsport Six into the E28 535 chassis. BMW started doing this around the same time, which I did not find out until 1987 when they introduced the US E28 M5. (I didn't have car magazine subscriptions back then.
)
The idea that a four door sedan could best world-class sports cars was very appealing to me. I still like that idea, and will own an M5 (perhaps more than 1) at some point. Right now it is part of a 3-car fantasy that I have (and if I could afford to keep 3 cars right now I would get one) as an occasional driver. Indeed, the M5 is one of the few cars that I can imagine owning for decades (the NSX is another).
You should pick up a copy of the book entitled simply "BMW" that is available at most large chain stores for about $40. (White cover with BMW in black or blue IIRC). Inside that book are many fantastic pictures, and a one page snippet entitled "The Cult of the M5".
