hello guys girls and guru's lol

ive just been informed of a mk 3 escort 4wd rally car which was apparently built FOR ford there was a debate whether there was 4 of them made or 6,

thats not my question tho my question is dose any one have any info on these cars at all spec or pictures or even just value? and also is there any way of distinguishing its a genuine version? ive been told they look like a basic mk 3 xr3 or rst

the reason im asking as i may know where one is and aparently its been sat for a while so im hoping to purchase it but dont want to be buying somthing worth nothing!

thanks in advance Tony
