Smell is such a characteristic of cars that rarely gets talked about. My old Fiat Panda 100HP from 2018 smelled identical to the late-80s Fiat Uno my mum used to have, my NC Miata's interior smells just like my last NA, and my Peugeot has a smell I've experienced with loads of old French stuff.

Every 1990s GM product smells the same, no matter the age or condition.

Every 240sx I've owned smelled like varnished gas and bong water. I'm not saying it's science but 9 is a pretty big sample size.
