One of my racing buddies had a string of car detailing shops called "The Last Detail", and was into open wheelers. He usually towed a gooseneck 40 foot trailer with two or three cars and all the pit stuff.. But at some of the smaller events where he was only going t bring one car, he towed it in what looked like a snowmobile trailer. He used a nicely restored '53 Chevy pick-up. Painted teal with a white roof, it had white leather interior. I wouldn't let greasy pit mechanics ride in something like that, but his shops always kept it in show condition.
The CEO of the facility I'm in drove his Lambo the other day, covered in snow. Obviously, it is parked outside. Might be his regular driver. A guy I knew from the Ferrari Club had a 365GTB4 Daytona as his regular driver. When he died, it had 190,000 miles on it.
