Neil,
There are a couple on the MMC website car finder a 4.0Ltr high spec at 45k with very low mileage, the other Cream one at 35k good mileage but a little accident history but reflected in the price and you get 4 new wings and crosshead for that. The 3.9Ltr is the best unit to get and ideally 1998 onwards you can guarantee the stainless steel firewall and inner wings then. You get the superform wings as well which are better as the earlier cars had spring steel folded into the outer lower edges of the wings and suffer badly with galvanic action in the wet and a smell of salt around is not good and white powder is the giveaway.
I'd be inclined to give Henry a call at Williams and let him know what you are looking for, he is a great guy, I bought my 4/4 Sport from him when they were based in Bristol brand new out of the showroom he is a pleasure to do business with and most helpful. He is a member on here but no time to contribute he is a busy guy with a young family and still races when he can.
Good Luck
p.s. Unless like me it's a V8 or nothing, this Roadster is known to me and also has a high spec and has been nurtured but used regularly
Roadster It's at Perranwell also a nice garage to deal with.
