Roush Mustangs are awful looking IMO, because I think body kits are silly boy-racer stuff.
With the new 2015, the exterior is a step backwards, but the interior looks great. I do believe the performance won't be that much better than 2011-2014s though.
But, I could be wrong. With new suspension all the way around, it could be a big improvement.
