Welcome. Yes, sometimes you might think Triumph production began with the TR2 and ended with the TR8... okay, I guess it did end with the TR8 but there was so much before and elsewhere in the story that doesn't get much attention in the U.S.
There is another 2000 Roadster owner very active on this forum (Wayne) -- hopefully he will find you soon.
They are delightful cars to behold... we have one in our local club. It was the object of a tech session (steering box rebuild) a month ago. A challenging project since parts are not as readily obtainable as for the TRs.
There is a fellow on the left coast (Encino) who often shows up at Triumph events with several of these. Always draws an admiring crowd.
