anyone on here got any ideas on wether or not a standard 3dr sierra should be returned to factory spec or turned into a cosworth replica. after reading many replica 3dr threads on here and other forums someone always posts "put it back to standard". i am in the position to do this (luckily) as i was going to turn 3 door 1.6 sierra into a replica. since this purchase i now have 2 genuine shells although 1 is for my son. what is everyones opinion on this thought. anyone know what a perfect condition standard 3 door would be worth compared to a cossie rep. most of the parts would be cheaper i'm sure (i already have a few). the only downside i could see if this was done and possibly sold after, i would bet everything on someone buying it and, guess what?, turning it into a cosworth replica. have any of you got any pics of 3 door sierra when they were new. any ideas on how many standard sierra 3 doors left that haven't been modded.
