I fully understand trailering a car say to Carlisle from a long distance, but can "safety" really be considered? Do you realize how vulnerable they really are? And towing a car actually leaves you very limited options for any evasive action with the tow vechicle. You get that trailer in any amount of fish tale action and beleive me you better have some experience with pulling a trailer! Trailering will mayby keep your car cleaner, and certainly keep the miliage down, but safer? I don't see that as being true. Perhaps CamJam could explain better than I.
While I cant say it's safer to tow, I dont think it's less safe either. If you are a responsible driver, and use the right equipment, it's not any less safe to tow as drive the car. I have a enclosed trailer, so that limits greatly the exposure to rocks and such when driving long distances.
My rule of thumb is usually if i can drive there in a hour or so, I won't trailer. If I'm going to be at the place of the show for more than a day or two, I always trailer since i have a place to put the car in the event of rain.
I think most of the comments so far have hit what a trailer queen is....a car that is rarely driven on the street, and has become for all intents and purposes a display car, not something that is driven.
I will always drive my cars locally....to me thats what's fun about them, driving them! I probably average around 1000-1500 miles a year.
