Contact Iain Cowie of ICR Motorsport as he knows where most of the good and not so good cars are, and if they are for sale.
You could always check out Autotrader.co.uk, fastroadandtrack.co.uk, racecarsdirect.com and pistonheads.com, but beware if buying a car from an english series as the rules that they run to (and break) are different to the ones in Scotland.
Any car which I have seen from England has required quit a bit of modification to make it legal in the Scottish championship.
Good luck in your search dodski, and I hope to be racing you soon
I have an XR2 for sale. I binned my other XR2 last year and then found a mint shell and have fully rebuilt it. The shell is immaculate, I have had a full welded cage put in along with having the car completely seam welded throughout.
The car is equipped with full LEDA suspension and has an ICR racing engine.
It has never been raced (due to lack of funds) and I am confident to say is one (if not the) freshest XR2 out there.
If you are still interested give me a call on 07553 360814.
