Lets see here... I carry every tool required to tear that poor car down to nothing but scrap! The tool bag never leaves the trunk and doubles as my wrecker ammunition
That along with at least 1qt of oil, spare ign coil and wires, coolant, grease, brake fluid, spare fuses and relays, jumpers, hurc straps, and 10L of gas. Usually filled with additional tools I need for work on the car during night shifts. Currently my electrical tool box, drill set, and a sh!t ton of audio wiring.

But no spare tire. I blow a tire and I call CAA.

I think my record time for an engine pull was just shy of 2 hours.
