Drive it on rare occasions. I don't care how careful you are it will get dinged, dented and damaged. Worse yet, some A-hole ,may key it for spite if it's left unattended. My Mach 1 gets out of the garage about 10-15 times a year. Sometimes for a short drive and sometimes for a long one. I never leave it unattended and if my wife and I go into a restaurant to eat, I sit at a window where I can see it. I know this all sounds very silly but the sentimental value of this car is well beyond ANY monetary value and if something happened to it I'd be sick.
It's not that I've got 30K in the rotisserie resto... It's the fact that the car means so much to me. I've known this car since new and a good family friend took this wide eyed 10 year old for a ride right after he bought it. This car started my love affair with performance cars.
It's yours, do as you wish. There's a lot to be said for having an ultra nice trailer queen and there's an equal amount to be said for having a spectacular driver. Buy/build a really nice driver and pull your trailer queen to the shows. Then you get the best of both worlds.
NOW , go explain that plan to your wife !
