Thanks, Chris, I may take you up on that offer, I'm haemorrhaging cash at the moment. These cars are more expensive than a Ferrari! Work is a week from hell next week so I'll give you a buzz next week if I don't get sorted.
Thanks, Rusty, I like the sound of the fan belt thing, it's something I've not checked so worth a look. One of the cars is the one that engine previously blew up on and was 'rebuilt'. It has never run the same and leaks oil badly. The red light is always on so it's in line with what you've described. The other is one that has just been recommissioning after 28 years in a garage. It runs super for a few miles and then cuts out. I don't think it is the thermo stat as I have wedged the flap that Chris describes open with a bit of wood.
Heartbreaking really. We don't get many driving days in this country so it was a shame to miss out.
The rusty red car came to the rescue, though, so we finally reached our destination albeit 3 hours late!
