Difficult ...
Well .... cool concept; as a Mustang fan, I thought this would look great on the shelf.
The engineering, not so much ... Doors, hood, trunk lid don't line up well. Door panels need adjusting. Inner rear panels need serious filing. The trunk lid hinges cause the rear body to sit a full 2mm above where it needs to be, and requires MAJOR modification.
Steering .... works, after a fashion. Tie rod ends are SLOPPY. Lots of chrome parts that shouldn't be chrome. Exhaust pipes don't quite line up to the engine; the muffler location is vague at best.
I got so frustrated with it that I packed it up and set it aside, something I've never done...
Nice detailed model
With opening Doors, Trunk, and Hood a very neat model. Also comes with 2 different tops so you can make it Convertible, Coupe , or Fastback
