Our ae92 Corolla does this, but both MBs don't. All cars are in CA, US where the weatheris dry and are in the same household. Even with the AC lowering the humidity in the cabin, my 300D doesn't have any static shock, which is a good thing when filling up (self serve). I'm more concerned of the Corolla, since my mom drives it daily.

Recently I didn't notice getting shocked on the Corolla, however. This probably is seasonal, dahil nung summer and spring lang malakas pero ngayong fall and the coming winter, wala.
