Curb weight on the `10 appears to be roughly 3,533 lbs., compared to 3,450 for a 5-spd `05-`09.

If I remember right, no more than 50lbs added.

is the weight of the new mustang about the same?
Someone correct me if I'm wrong but I think it is to be a little heavier than the 05-09 models, but not much.
