I had a buddy that had one some time back. It was probly an early 80's. As long as I new him he could never drive it because of a cracked windshield. The glass was dam near flat and everytine he went up his driveway apron it cracked again. I think he had something like four windshields in the car never making it out into the street. I dont remember the history of the car as to weather it was ever in an accident or not but thats very possible, he was quite young to be owning a Lotus. I know what your looking at is no where near the same car. I would do what you did and get a mechanic that only works on Lotus who knows what the market is and what to look for.
Sweet looking car.
