I assume you've all seen Broughy's latest performance testing video on Youtube? He includes the 4dr Felon because he hadn't tested it previously, and found it was a fair bit quicker than the GT and a solid second in class with the hard top Zion. Still not quite as quick as the Exemplar, but competitive.
My first car was a Felon and I confess I sold it before we were told we were getting the chance to buy a second garage. It was dark blue metallic, on stock rims, visually unmodified apart from lowering. This weekend I've acquired another (had to buy it, then they started spawning everywhere, typical) and it's a very dark blackcurrant metallic, with Lozspeed Baller SUV rims in stone silver (virtually the same design as the stock rims but dished with a polished rim); again, no other visual mods. It's fantastic. Still love it.
