its prob a motor sport shell mate they were non sunroof

also some form of hpi check or the log book should show what the car was or is fwd 4x4 etc

also check for welding that doesn't look factory paint there is loads of stuff to tell if its not a shell ie one thats been mate from 4x4 floor pan and fwd shell

in this country cars built from motor sport shells have to go on a Q plate which are assigned by the dvla
