Really any musical instrument I guess. But I was visiting some family friends today and was trying to explain that the three vintage Chrysler’s in their shed had a lot in common with the guitars (and mandolins, and basses, and etc) in my studio. Each year of manufacturing means something. You can keep them stock, you can hot rod them. You have your Japanese made addicts, and those hat think Japanese guitars are junk. (For example). A Les Paul 59 is a Cadillac. A Gretsch is a Buick. An Ibanez is a Honda. A telecaster is a Ford. Or a Chevy. A strat is a fair lane. Or a mustang. Etc etc. I know my examples aren’t exactly accurate, but you get the idea. Colours, parts, widths, lengths, preferred part brands. Tyres, strings, pickups, engines, Ford. Chevrolet, fender, Gibson, etc etc... Any car nuts here who could explain it better?
