Yep too many people not reading the ad, it's not just £20k for that heap of scrap, they will 'restore' it for the price, even though that's very steep!
Surprised no one has mentioned the alleged mileage, I doubt that's correct though, too many owners for a start. If you want an S1 buy the one in the for sale section, far tidier already and it's about £17.5k cheaper.
