GM past about 1978 is almost entirely metric too, depending on the engine combination and specific plant. I took an 1984 Cadillac apart a few weeks back and the entire drivetrain is Metric while most of the body stuff are SAE/inch. Very confusing amalgamation.
We also use it for engine displacement.
Basically all cars are all metric (for fasteners, etc.) these days. Even my '90s Ford is metric.
The lugnuts are the only place you will find SAE on a modern passenger vehicle.
Don’t you just love how tire width is measured in millimeters, but diameter is measured in inches?

3.8l was almost all metric except for the intake bolts for some reason.
You will never regret buying a lot of extra 10mm sockets and wrenches. Bonus points if you have some spare 12s as well.
Nah, it’s 13mm that’s the other common size. (Why? Because it’s secretly 1/2" in disguise, LOL.)
I have a '93 Ford and it’s a bastards mess of SAE for one bolt and Metric for the next one.
