My wife had a 1977 TR7 (she bought it in late 1976, and she & I knew each other but were not together at the time - had we been, I might have suggested a different purchase!?). For the first 18 months or so, it ran reasonably well, then all hell broke lose. She must have spent several thousands of dollars in the next year or so on repairs/fixes to failed systems/etc.
We came together in late 1979, she still had it and drove it until June 1980. We moved to Vancouver then, and we had it trucked to Vanc and sold it cheap to some impoverished SFU student. Pity him, but we were rid of it for good.
Not a good exercise at all.
Were the V8 TR8s better? Don't know but that TR7 has to rank with the worst cars I have ever experienced in my life.
Ovr I could just copy your post ! We had a '76 TR7 bought new in 77.
Transmission had to be replaced after 4 months as 1st/reverse gear failed. Waterpump was replaced about 6 times as it continually leaked. Wiring to one of the pop up headlights chafed through. Ignition module failed.
Mrs tpl loved it, I hated it. We traded it for the first of the fwd Mazda 323s which was not a bad little car. ( it was in fact called the GLC as in Good Little Car )
