Are you buying the car from another LT member? Its a small community and we often know each other in certain areas and can vouch for the persons ethics.
Post pictures, we may know the car or have pre owned it and can give you some background.
To be honest, a dealer is a good idea but find somebody here willing to go look at it and test drive it for you. A Lotus owners eye is going to be much more critical than a dealers. I did this with both my cars, using fellow LT members, paid them $100 and was quite happy with the outcome.
I know Ross Calson is in Ft. Collins but know he has been busy lately and have not seen him much lately. You can try to PM him.
