I bought my TR 7 brand new off the lot in April of 1980. I have enjoyed it for many years. I upgraded the stereo with a bigger AMP and better speakers. (I still have the original radio on the shelf.) Other change is a manual choke and no longer has the Bosch fog lights. After a minor fender bender, it was repainted.
Pretty much in original condition other than these few changes. For the past 20 years, it lives in heated garage and I drive it a bit in the summer. I have it regularly serviced by British-European mechanics.
