Thanks for all your kind comments.
Engine work at a standstill at the moment while we await a part from the factory. Hopefully it wont be long now.
As with all elderly cars they need good regular use, and my engine has suffered as a result of under use over the past ten years or so. I did more miles in the first week of ownership (480m) than the car had done in the entire past seven years.
Its fine keeping a car in a carcoon wrapped up in cotton wool, sure keeps them shiny, but use it or loose it as regards the engine.
