Air-cooled VWs (Bug, Ghia, Thing, Bus, Type3) wave like 99% of the time to each other
Jeep Wrangler Drivers often wave to each other
Corvette Drivers (usually excluding the most current models) often wave to each other
There are probably others
Anyway I always wave if I see a subaru (excluding soccer moms). I usually get a wave back but WRXs are still pretty uncommon in Texas.
It is funny when I go back and forth driving my Karmann Ghia and my WRX I accidentally wave at WRX drivers in the Ghia and at Bug drivers in the WRX... I get a lot of WRXs racing me in the ghia that way and a lot of confused Bug drivers
