Cambelt is 72k or 5 years - whichever is sooner. Having tensioners done at same time would be ideal.
Steering column gets worn and play in steering develops
Power steering pump is noisy.. this is normal though unless its silly noisy
Sunroof can leak.. 90% chance it will if it aint been fixed.
Clutch go about 90k normally. If its stupidly stiff, it will need changing else youll go through cables like anything.
There are loads of things to check. Most are pretty much things youd look on any car. Depending how you look at it, you should be able to get a good idea of how its been looked after. Even if it doesnt have SH or many receipts, it can be pretty clear.
Bear in mind it took me about 18months to find my Williams, and buying it is the same as a Valver.. so you can be picky if you want and wait ages.. guessing most people arnt tho, hehe.
If you get one which is problematic mechanically, it will annoy you. They arnt cheap at all.. mainly because anything under the bonnet is a damn long job - quite a few bits which would need doing require the engine to be out.
Best advice is take someone with you. If Mat didnt go with me, Id have probably bought anything. Two people can spot a lot more than just one so its definetly worth it.
You could look at Mats 2.0 16v.
Had a lot of the major stuff done (cambelt, clutch etc..) so good to go. You also get the added bonus of a 58k Williams engine..
