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.
Tire treads are measured in 32nds of an inch, brake pads are measured in millimeters, brake rotor thickness is usually inches but sometimes millimeters, brake rotor diameters and offset are usually millimeters but sometimes inches, alignment measurements are usually degrees or minutes of angle sometimes also inches, pressures of coolant or tires are psi or bar…
We also use it for engine displacement.
Basically all cars are all metric (for fasteners, etc.) these days. Even my '90s Ford is metric.

3.8l was almost all metric except for the intake bolts for some reason.
I have a '93 Ford and it’s a bastards mess of SAE for one bolt and Metric for the next one.
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.)
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?
