In regard to weight, here's a copy and paste of what I wrote on page one;
"Considering the M6 convertible/coupes actual competition is now the Bentley GT V8 convertible and coupe, CL63 and SL63 it's weight is not bad at all. With the exception of the newly designed SL the M6s are much lighter than the others. When compared to the Jags and Astons it's heavier yet *performs better and comes with more bells and whistle than are even offered on the two respective brands."
I can't tell why others would but I can tell you why I would buy an M6 over the rest of the 6 range, (not that there's anything wrong with the rest of the range):
Carbon roof (coupe, tech aside I luv the look)
Wider stance = great road presence
Wider wheels and tires
Carbon trimmed interior
M seats
More power/torque(without aftermarket add ons)
7 speed DCT(although the 8speed is nice)
0-60 in atleast 3.7(coupe) considering its M5 counterpart can do it
This is a short list, I left alot out....
This car can go full on(raw power with great handling in comparison) to full off(max luxury). To me this is a more refined mature mans/woman's M3 now M4. Someone who doesn't care to track the car and drives at or below the speed limit mostly but on occasion reverts back to his/her youth on an empty stretch of highway.
That's where I am.
I'm the same guy that would buy a CL63, I just like the BMW better.
