Stephen,
I think you'll need a bigger car

Looks like I'm going to need to go to: http://www.usedcoachsales.co.uk/ haha

A few disposable latex (or non latex) gloves can keep your hands clean and dry if you need to fill oil, or other fluids.
If you need to change your tires, a pad for kneeling or a couple of the pads used by flooring installers to strap on to your knees can help.
Some sort of traction pad or a container of kitty litter can help you get unstuck from ice or muddy situations.

if we go out at 2am and end up in Scotland or Wales (this happens way more often than you would think)

If you start out in America and end up in Scotland, you have definitely gotten lost. If you start out in America and end up in China, who will believe you even if they can understand you. If you start out from home and later notice 2 moons in the sky, give up all hope of getting home.

I know you said multi-tool, but to be more explicit about a few tools that many don't think about until its too late - window breaker, seatbelt cutter, and pry bar.

Don't forget the acetylene torch in case you have to burn your way out!

And don't forget to put them in the boot since they're not the kind of things you want flying around in the cabin during an accident. 

For some reason all I can think of is Ford Pinto.  The remarkable engineering feat of having the top of the gas tank and the floor of the trunk one piece of metal.  That one case made Gerry Spence a household name(at least after the 60 minutes show profiled him.)  Speaking of compressed gases in the trunk, a guy I worked with who scuba dived as a hobby claimed he had a tank let go on him one time.  He said it borrowed 8 feet into the sand by the time the pressure was exhausted.
