Thanks Guys. I think possibly I might need to take someone with me who knows more about these than me. I imagine it is easy to get a little misty eyed about them without looking at the practicalities. Will put some feelers out for some V8 guys around the area.

The current owner works for the ambulance service in the fleet department, so servicing and fixing them and also fire engines I think when they come in. Lovely guy and from first impressions very genuine.
