Good luck with the car. Absolutely fantastic. My tyres went off at 7k miles and they were like F1 from when tyres went off a cliff big time. They still had loads of tread on them both front and back to look at but car was all over the place and I had to get new tyres. Once on, car was back to it's best, so it's really sensitive to the Corsa tyres.
Re price, have been too busy with work to put mine up for sale to make way for the Indy but I am planning to put it up for £86k so seems your price is right...
Good luck
