Looks like a well engineered project to me.
 
He's obviously stinking rich. Remember that to him, the Lambo probably has as much monetary value as a £500 track shed project to any of us. He's probably got another dozen similary exclusive cars to play with. It's obviously just a toy.
 
Also, as far as I can tell (I could be wrong) he hasn't turned it into a Mustang. He's put the engine and drivetrain into a Mustang. Looks very well finished to me. That's rubbish but put a VAG 1.8T into a Clio and it's a heroes car? 
 
I bet anyone on here would wet themself if they had a spin in this
