Now there's one that ought to have potential for future BTCC-themed models. How long do you reckon before we get a Richard Longman/Patrick Motorsport Mini..?
Then again, they've had the Rover SD1 tooling available for several years now, and still no sign of the BTCC version...
There's also a Mk1 Capri, albeit in RS3100 guise
