Hi Doug,
Many thanks for your prompt and detailed reply. Much appreciated.
I'd taken a guess at £5K, so probably slightly high, but in the right ball park. Car condition is still all original with a few areas of surface rust I need to catch. Also a bit leaky on many seals, both fuel system and engine gaskets. I'll probably do some of these jobs before taking it for an MOT (although not needed now) to make it safe to drive as I don't want it catching on fire just popping for an MOT.
Thanks again
Jim
