This kit has a fair amount of extras with wheel and tire options as well as engine options. The detail is to be expected for a tooling of this age. My largest complaint its the rake of the a-pillars/windshield is too severe. Once the kit is finished, it just doesn't look right. As long as AMT has been producing various 1st generation Mustangs in kit form, I would think that they could get the body shape much more accurate. It can be fixed with a fair amount of plastic surgery
