I've just been to look at a white XR3i cabby with an S2 engine in and a full S2 kit (88 spec I think)
Looks clean enough, but overfuels like a bastard.
The only real bad bits I can see are the overfuelling problem and it needs a new roof the roof needs repairing (small split next to back window.
Its been off the road and parked under a tree since 2004, and apart from a bit off moss on the bonnet and round the door rubers it looks ok.
Is it worth the £400 he's asking?
Sorry to ramble, but I know sweet FA about RST's
