Mirage Motor Company "Not Mustang"

This is my first complete car that wasn't just trying to get super high HP numbers. Any suggestions would be appreciated. I haven't installed the mod pack yet so this was done with default fittings. I think the back should be raised up and the front of the cabin pushed foward a bit as well. Really would like to see it a feature to be able to adjust car model after trim is complete to fine tune any areas you might have over or underestimated for visual appeal.
Also, should I resize these, and should I include the engine and model files as well?
