ok ill try it again for you
THE SIERRA SAPHIRE COSWORTH WAS MAD IN 1988 AND ONWARDS,,,, THAT MAKES IT NOT POSSIBLE TO HAVE ONE ON A D REG AS THAT WOULD MEAN THEY WAS MADE IN 86/86 ERE AND NOT 89/89 EREA
HENCE WHY THERES NOT MANY E REG ONES COMPARED TO F REG ONES TOO
hope that explains more
s2's where made in 86 so could have got a early registered one supose but the 88 model year makes it not possible as e's and f's where that year
show me a d reg saph cossie and i will admirt defeat but i bet nobody has a GENUINE one
