>> car funds <<
That's a great idea, similar to the art 'funds' out there. It might suggest a top/frothy market, but as you said, if stocks go out of favor then the high end art and car markets could be the beneficiary, at least for a while.
Years ago I met a local guy who specialized in British sports cars, and in addition to two XKEs, he had a Sunbeam Tiger and a TR-250. I remember the TR-250 was similar to a TR4 but with a 6 cylinder, so was basically a forerunner of the TR-6. The Triumph Stag was another interesting car of that period, as were the Lotus Elan and Austin-Healey 3000, which were all pretty affordable.
I had several motorcycles back then, which were cheaper than owning a car, but several friends had cars which went on to become classics like the 67/68 Firebird, a 66/67 Pontiac LeMans, and a neighbor had a Porsche 911-S with the optional 6 cylinder (4 cyl was standard at the time).
A local doctor collected cars and his brother restored them, so he'd have a rotating stable of sports cars. He inherited some serious money, and probably had 6 or 8 cars at any given time. On nice days he'd park them in back of his office. I only saw his Ferrari 512 Boxer and Rolls Corniche, but at various times he also had a 246 Dino, a Maserati Merak and Bora, a Countach, and a Bugatti. He also had several airplanes. Not exactly Jay Leno, but close enough :o)
