I've just made sure of the rules, and I am within them, you can buy this car direct from the manufacturer... but you can also (like I did) buy it in component form and build it yourself.
Since I live in England, yes, it is a British car, so you have to pay for it in pounds.
Edit: It looks like I'm going to have to abbreviate this one soon...
and slightly cleaner, the day it went to be tested for registration:
It was built with the 2.5litre V6 engine, and with sport cat, straight through silencer (pretty much) and performance filter it put out about 200hp. Weighing 830kg wet it would outrun pretty much anything, including that TVR Griffith in the photo, all the EVOs that turned up to that trackday, and most notably, a very annoyed 911 Carrera driver.
