I never understood the watch thing. Mechanical watches are a Rube Goldberg way of timekeeping in the age of electronics. I was always hell on watches, so kept to cheap Timex or Casio watches. After I started carrying a mobile phone, I stopped wearing them entirely.
I do get cars and motorcycles though, at least to a point. Even something as simple as accelerating onto the highway is a vastly different experience in a Mitsubishi Mirage compared to doing the same in a V6 Camry, Z06 Corvette, or Tesla Model S.
After a certain point though, you're well into rapidly diminishing returns in terms of performance /dollar, and it just becomes another financial dick swinging contest.
