to me they seem like a specific interest, a hobbyist thing. at least to a degree. i mean i guess a lot of people can appreciate a good-looking car. my mom and i are looking at them all the time. but i've never really been interested in car shows. seems a bit geeky and/or materialistic or something. and cars are such an arbitrary human technological invention, when you get down to it. yet we seem to appreciate them almost like we'd appreciate human bodies or animals.
