Hi Andy
There are lots of threads on here including mine and Jeemy's, to mention 2 recent ones, which go into a lot of detail about what we found when we started looking closely at our cars.
viewtopic.php?f=79&t=19040viewtopic.php?f=79&t=20848Depending on how far you want to go, I would recommend checking the suspension thoroughly. If they are in good condition, it is always a good idea to have stuff like wishbones blasted. You can then apply the protective finish of your choice, powder coating, POR 15 or whatever. Don't use Hammerite, it is carp!
I don't know if the rear is more prone to problems or not, my rear wish bones were shot but one of the front TCA's had a serious weld patch on it so that was junked as well. I guess everything has to be treated on condition.
Only the upper raft bushes on my car were reusable, I had to replace the rest. The rear disks were beyond saving but have now upgraded the brakes front and rear. Power steering hoses, cooling hoses, radiator, condenser, brake pipes, master cylinder and alternator had all seen better days and were replaced.
This might sound like a lot but as I said, depends on how far you go and also, what you find. As you have spent 2 years on an Esprit then I guess you know what you are letting yourself in for.

There is a lot of advice and help on this forum, don't hesitate to ask or PM.
I now have a car which handles and stops, look gorgeous and have been using as a daily driver in Europe for the last 3 months. So the engine is ready for a rebuild and there are other things I want to do but in the end, it is worth it.
Good Luck!
