best thing to do is post as much info as you can to help sell it, some more info id want to see when looking for a cossie is

injectors?
clutch?
turbo?
block?
when & what mileage was the motor rebuilt? who done the rebuild and most importantly what was done for the rebuild. any receipts?

i would then decide if its worth looking at, i'm sure other would agree.

My advise would be to put the plate on retension as you never get any money for private plates. sounds like you've been honest in your advert which helps!
