take out the drivers plascit carpet trim and teh drivers seat and check that floor isnt laid in or welded in, ive had them with 2 or more re fitted chassis numbers! one welded and one glued over that on the last grey one i bought to break
if you are paying good money its best to know its legit, if its a bit dogey (albeit a longtime ago maybe) thats then up to you if you want it, i really wanted a clean 1.4s fiesta recently but it was blatantly a ringer so i couldnt do it and i let it go to some other mug, i doubt it will get pulled in but then i dont want a ringer to ride around in
