It wasn’t all that long ago that we brought you the Galpin GTR1, a 1000 plus hp supercar based on the Ford GT. And now, after an initial debut at the 2014 LA Auto Show, the Galpin Fisker Mustang Rocket is in production. This limited edition super Mustang was designed by no other than Henrik Fisker and in top form boasts 725 supercharged horsepower. The already aggressive profile of the Mustang in augmented by carbon fibre body-work and 21 inch wheels wrapped in Pirelli P-Zeros. The optional Gran Turismo package adds 15 inch six piston brakes to scrub off the miles per hour in a hurry. Save up your dough though as this Rocket will set you back $125,000.
