Hi there,
Check out
www.cmldistribution.co.uk as this Car is available in the Uk now and personally i think it's a good deal - especially to get back into racing on a budget!
Only other thing to do is weigh up the costs of buying a second hand car and all the bits you need to go with it as i think the Electrics that come with the RS car aren't the best but it all depends what sort of use you want to get out of the car i guess?
