Do you let your old engine warm up or just get in and drive?

Being a south Fla resident, anything below 60F is "real cold".
But my reason for liking this response, few seem to care/note much about the rest of the drivetrain, that "easy" above also takes into account.

Yup, like I said, I idle it a bit then drive easy a few miles first. 45 degrees & colder I'll do 1 minute warm up, but the trans fluid, especially manuals, & diff fluids are still cold no matter what. Engine oil will warm up pretty quick, but some like to warm their cars up well. Just don't start up & GO, like I see people do with their new cars, that CAN'T be good, even on a warm day. Just my opinion though.
