Bonkers! Colour and car, just about the best place I could imagine to be. I was lucky enoough to drive a mates, and I can't imagine that jet fighter feeling ever getting old. Well done!
It's a landmark car in incredible condition, if I was a rich collector with space I'd pay that. and I'd bet in another 20 years it will be worth double.
If you decide to weigh them its only really 10 mins per corner. Also, check for cracks and nicks, scoring etc. At that level of investment a set of bad brakes would not put me off an otherwise nice car though. just my opinion FWIW.
