Not an expert on these but i think their an insurance friendly version of the mk4 xr3i (bit like the mk2 Fiesta 1.4 Sport)

Is it injection or carb? the engine will either be XR3i (injection) or XR3/XR2 (carb)

Not sure how rare they are, if its untouched keep it that way as alot of them get made into XR3i/RS Turbo lookalikes
