Hey Chris,
How about *still* being happy with 470bhp and the new wideboy look and using it for day to day driving (when your home) and building yourself a bespoke Track car ?
The white one is sooo clean and reliable and seemingly pulls like a train, why change it or risk damaging it on track etc...??
Then you could......take your time, get a shell for Steve to cage and build it from the ground up... Then slot in an engine of your choice for your needs.. Best of both ? Just a thought.........
Mind you, it IS easier spending someone elses money
