It's not drastic. The body is pretty much ok aside from the small ding in the bootlid. The front bumper got pulled off when a sturdy hedge hooked inside the wheelarch and I kept reversing, so some of the clips are broken. The chrome trim has lost its lustre in places so needs cleaning back and re-lacquering (or replacing). The rubber moulding on the driver's door keeps coming away (clips again). Inside, the leather could do with some treatment. The steering wheel leather is tired. The rear screen got broken and the headlining has a small tear as a consequence. Mechanically, there's a small oil leak from around the top of the engine, some of the multi-link suspension components have seized and could do with replacing. It needs a new exhaust soon.
I spend all my spare time restoring old racing cars, so don't have the time or enthusiasm to work on the S8. I don't really like working on road cars. However, I can afford to pay someone else to do the job. I'd probably want to strip back the mechanicals and replace things like subframe bushes. The standard suspension works well but the dampers are 20 years old, so again, I'd replace them. All the suspension kits (H&H etc) seem to involve lowering the car which I don't want to do. I've already had the brakes re-done with dimpled/grooved discs and red stuff pads.
So my ambition is to get the car back to how it was without losing the originality. I only paid £3K for it (with an S8 number plate). The car, even in its slightly care-worn state, is a truly lovely thing. I don't thrash it (I have the race cars for that) and together with the A2 it makes for a great combination day to day, as well as a tribute to Ferdinand Piech's "I can do what ever I like and nobody can stop me" design ethos.
