my personal opinion owning one is that they are a gd car, and no way are they slow, there not the fastest but they are fast in there own way, i can easily get 125mph out of mine and gives the newer cars a run for the money, st170 aint got nothin on the 4x4 nor has the fiesta st, handles very well, can put the power down round corners, yes the running gear aint the best but if you look after them then there is nothing saying that they wont last a long long time, only thing they suffer with like all other fords is the rust issue, they could of done with looking a bit sportier coming off the production line but all in all i think there a gd car, being all 500 ever built i think its worthwhile having one as they are very rare and to restore one and have them sitting they will become a collectors, could be wrong but i think the rs2000 4x4 is all in all a very good car
