Sadly there have not been many outings for the lotus elan +2 on film despite it seven year production run. The instances are confined to TV, They are:
In the seventies Tara King drove a red Lotus Elan in one episode of The Avengers.
The popular sixties series Randle and Hopkirk had two episodes were a Lotus Elan was used, a red one, presumably the same one. There were only one or two scenes in both episodes were the Lotus Elan was used.
Interesting in all occasions the Lotus was red and all the cars were driven by attractive women.
