RE: Trading In
I would trade in any day, M3's are great cars and unlike my signiture have damn sexy lines. They go heaps hard( as i'm sure you have found out) and do it in style, but as the previous bloke said they can give the spinal region a workout but thats because it's a sports car not a luxury exec mobile to transport you in comfort, but thats one of the best things i think because if you DIDN'T have the hard suspension it would handle ummm...no where near as well and that pinpoint steering you have no doubt fallen in love with would not exist. But yeah it's a trade off between pure performance ie acceleration, handling, braking, grunt and the howl of the engine and a in comparison tamer cruise ship.
But just because you have driven an M3 doesn't mean thats the only car for you there are cars out there that do it just as well, i'm not sure on the pricing but you could also be looking at an SLK AMG. Below is a 2000 model--> want my advice go sports
