Tiff
I have only broken 2 x 3 doors mate!
Neither were anywhere near standard being my white one and Steve 3dr als's!!
Both of the above had loads of uprated bits of good value as well as the stuff that only 3 doors have! All the parts that are common to all Sierra Cosworths obviously don't get as much so a lot depends on the standard of the car you are starting with!
Mine for instance would break for circa 15k if i wanted to go that route
