Back in 02 I bought my 300M. Loved the beans out of that car until it came time to look for something new. I drove that car for many years and I got used to the size and the comfort. It's a huge change to switch from a larger sedan to a mustang. That's really the only thing I miss. The mustang (in comparison) has pretty much no back seat. I feel bad for whoever gets crammed back there. The lack of trunk space (also in comparison) stinks. My mother complains the mustang isn't as comfortable as the M, and I tell her they are two completely different cars and mustangs aren't meant for comfort.
When I was out shopping it was pretty much going to be a 300C or the mustang. I more or less went w/ the mustang because I didn't want to be in my 40's then considering a sports car. I think after the mustang, it will be another sedan.
