Was speaking to Sandy Forrest at the Track Scotland night last month, and made a comment regarding how I was amazed the SMRC XR2 championship was still running, given the age of the cars and the rarity of spare parts.
He indicated moves are afoot to 'replace' (or supplement) it with a new series using Mk1 MX5's - Similar spec to the MAX5 / Ma5da championships.
Could be of interest to some - Roundly similar cost-wise to XR2's, but front engined / RWD, so should be more fun to drive.
(I note Iain Cowie has built at least one car already...)
I'm quite tempted to sell the hairdresser wagon, get a Ma5da series car, and learn it at trackdays over next year, with a plan to take part in 2013 if it takes off.

For anyone thinking of having a go at racing, this could be a very good budget option.
