Truly one of the rarest Lotus cars in this country, with only 500 of any kind stateside. Even a Lotus specialist is not likely to see many.
Luckily they need little work, and the things they need are going to be familiar to any competent trusted mechanic. A timing belt/waterpump is the same as any other vintage Japanese car. I think the guy that did mine cut up a wrench to get at something or other.
Buy a copy of the factory shop manual, the most damage done to mine was people trying to figure out how to take things apart without instructions
