I had a slot car track exactly like Jays in the picture. In fact, it had the same layout also. My Dad used to have some 1/24 stuff, and when I was really young we used to go see some professional layouts and races that they would set up in a parking garage in nearby Lima, Ohio. The 1/24 stuff was really heavy, comparatively, and they really took some finesse to get around the tracks.
Then I got into models. At one point my entire bedroom was taken up with models, loaded on every shelf. It got to a point where I was building custom stuff with lacquer paint jobs that I would sand and buff to a glass finish. I detailed every wire and hose/line in the engine bays (it even had a hood release and cable). I even won a few contests with them. I still have the custom chopped top '49 Mercury I made that won a couple of them. It even has keys in the ignition
The last one I made was a custom '28 T-bucket that I made a special engine for, complete with removable heads to show the pistons (it even had a crank and rods, but not moveable), brass shim stock that I made head gaskets out of, drilled out ports on the intake etc etc, to make it look as realistic as possible, and even going so far as using mechanical watch hardware for bolts and nuts on the suspension and making braided line for the hoses. I was really proud of that one! Jeez, I spent a lot of time on that stuff!!..lol Once I got my license, that all stopped and the real stuff took over.
