I actually met a Jensen 541 once, several times actually... When I first moved to Ontario back in 2000 I worked briefly at a gas station... When a customer came in one time with a 1985 Jaguar XJ6, we got chatting and he mentioned something about a Jensen he had at home... Yeah, I've seen a few Interceptors and Jensen-Healey's before... My jaw dropped when he said he had a Jensen 541... Peter was a friendly guy who and said I was welcome to come over to his place, ironically a street I had passed through several times as a neighbourhood shortcut... It was a stalled, long-term, restoration... He moved to Ontario from England in the mid 1970's, his father - a car collector - allowed Peter to bring the Jensen to Canada, he drove it for a year or two (including winter) then parked it for many years...
I think my interest got him going a little on the restoration, although at the time I moved back to Alberta three years later he wasn't finished yet but still working on it at least...
