Slightly mistook indeed
The prime edition did come in 2 & 4wd and in turbo & non turbo forms & only in the RS series (as opposed to the X & G Series).
You are correct the primes came with wood grain as standard but it probably could be deleted when ordering...
If you have/had xenon lights, auto lights & super fine hard coat paint (check your back window for the SFHC sticker), then you could have a prime ed (the list goes on if anyone cares)
The type B is actually a 2 or 4wd turbo in manual or auto that was built "Pure for Customize"[sic] which came with steel wheels, no stereo, ready for the owner to make their own additions (see picture. sorry, no scanner)
Joe if yours has a factory LSD then it may be an S Pack.. does it also have fog lamps and heated windscreen/wing mirrors?
Any q's just ask.. I have detailed files...
