Hi there, thanks for the advice so far.
As for the S2000, I said I thought it would be a lot faster, and they were similar. That does not mean I beat him, as i didn't. He was trying though and maybe his S2000 had too many miles on the clock, or had been trashed a bit. My sport does seem much faster than I thought it is supposed to be, so maybe its had some extra tuning. I read its supposed to have a top speed of 134mph and 0-60mph in 9 seconds? I don't like admitting it, but we were both well over 140mph when we had to slow down for traffic and the is was still accelerating. We hadn't started from standstill but from 80mph, which I suppose lessoned his advantage. I realised it was a stupid thing to do that sort of speed, but its a new car and you have to test it out once, don't you?
How much did I pay? Well, after I have spent the money on the parts, and respraying the bumper (couple of minor scratches), service, tax etc etc, it should stand me at less than £10,000. For a sport with full service history, low mileage etc I don't think thats bad, especially now I have driven it.
5-spoke alloy for £50, that should do as a spare, where do you live?
