tbh mate if you got a donor car n transplanted it you'd be much better off just having the standard frst.
also insurance is going to be worse on an engine converted fiesta than a frst.worth a thought.also you'd be luck to get change from at least a grand
personaly i think ud get some good cash for your car as it is and put that towards a frst.
sleepers are cool but be realistic
standard looking fiesta mk3's look pants
