Loads of Mk1 FRS on the market at the moment and tbh you can easily bag an average miler or even a modded example for less than £10k as chop says - however don't be surprised if you see a few overpriced ones for sale as well as some people are still under the impression that they are still worth £12k+
Might be worth also keeping an eye on the For Sale section of the RSOC forum as there are normally a couple of decent examples there
