I am in the process of acquiring a 1989 90 V8 CSW, the car is mechanically excellent and looks great but I have noticed some pretty hefty corrosion on the floor pan under the pedals (OK inside but visible from under the drivers wheel arch). My question is, should I worry about this? It isn't really structural and the chassis, crossmember and bulkead seem solid. The vendor reckons a plate can be welded from the inside quite easily.
Advice appreciated (and be polite, the vendor reads this news group and is a top bloke, it's just that I haven't really got a clue about this sort of thing)
