I purposely purchased a TR7 to be used to go back and forth to work while I began a minor restoration on my TR8. Since I am a truck driver, I usually run back and forth to work on the weekends, so I still can get away with "classic" insurance and not break the letter of the contract, if not the intent. Saves a bunch of $$. I find that hopping into the 7 after a 5000 mile run in the 18 wheeler is very invigorating, not to mention a bit of a strange feeling!
Now that the 8 is running again, although not complete, that's what I use when home. I guess it will go down again for a while when I start the paint, and then I guess I won't be able to leave the 7 as it is and a new project will be born. Still intend to use it back and forth to work, though.
Back in the "day", I had a TR4 in which my wife and I honeymooned and used as our only car for several years. Never had any trouble, but, of course, they still had actual dealers back then. Wife got pregnant, couldn't get behind the wheel anymore, so on came the Opel (remember them?) Probably should have bought a Cortina, they were pretty nice little cars, too.
Just remember, ALL cars are meant to be RUN. You are not doing your car a favor keeping it closeted, only bringing it out for the occasional show or whatever. It's not really good for the car, and no fun, either.
