Thanks for the response.
Guy's, Who insures your cars and what restrictions are put on them?
My desire to go Lotus or Caterham may be un/misinformed; but the reasons are easy registration on the old Lotus Sevens, parts availability/interchangeability (with Caterham), resale, & insurability (questionable on caterham). If I was sure that I'd love this type of car then I'd probably lean towards the S2K engined clones and put up with the aggravating registration/title process
I think all the Seven's are either DM or EM depending on engine size and if they are NA or not so I plan on running DM on a regional level since I dont have the skill, budget nor the patience to constantly tune
