Oh and FWIW, you can get a good B6 S4 for under £7K, full history, 80K~ miles.
They have timing chains, not belts. The aux belt change requires taking the bumper off and headlights out because it is on the front of the engine, but the engine doesn't have to come out.
Consumables aren't too expensive either, as they are basically just Audi A4 bits for the most part, and the bits that aren't, aren't too bad either...
That doesn't mean its a good idea though...![]()
I had a B6 S4, lovely car but the engines can chuck up some monster bills, add to that never getting more than 200 miles from a tank and they aren't for the misers among us.
Lovely sounding engine when its running, but from cold start up the chain slap you get is so embarrassing, I would always wait for people to drive off from petrol station forecourts so they couldn't hear it, then treat them to decent sound from the exhaust rather than a bag of nails in a washing machine.
