06Reference
Identification guide
How to tell an original from a replica or later conversion.
Compared with a Grand National the WE4 differs in its interior trim, wheels and badging. Mecum lots confirm that WE4 cars use the Grand National interior and wheels, so documentation of the WE4 code is the main check.
