I put a fanny pack with a zipper around the passenger seat headrest (facing the back of the car) and put in 2 of each of the following short and long 3/8ths 10mm, 12mm,14mm sockets. I keep 16mm - 22mm 1/2" impact sockets as well. A 10mm, 12mm, and 14mm wrench.
Associated ratchets, zip ties, metal zip ties, and a foot of DEI sleeving.
In a little box in the trunk I keep spare plugs, hose clamps, wire strippers, needle nose pliers, an extending magnet, flashlight, vacuum caps, a spare cam position sensor, a spare MAP sensor.

Other notable mentions- a roll of shop towels goes under the passenger seat, jump pack goes under the passenger seat, and a spare quart of oil is tied up in a plastic bag in the trunk as well. A blanket and spare socks.

I've needed all these things and not had them in my life. Never again
