That makes me wish I lived in a town with lots of commuters (that are older than college-age). Of course, I'd have to paint over the bondo on my corolla wagon for it to work ;)
Let's see...I've got:
Cheap metric and standard combination wrench set
Cheap Multi screw driver
Metric and standard hex key sets
Crank flashlight
Framing hammer (because I didn't have a proper ball pein around)
Large Crescent Wrench
Generic Pliers
'Lectric Tape
A knife of some sort
All in a canvas HF tool bag ($3.99 with cupon, I think).
I typically also carry a spare belt or belts for the vehicle, a spare fuel filter, and a quart of oil.
In winter time, a tow rope resides in the car.
I posted a thread like this on the old board. I figure 90% (or some other large percentage) of roadside car problems can be fixed with a limited # of tools. I've opted away from sockets. I think the allen keys I carry are probably overkill (but they don't take up much space).
I want to carry enough tools to be able to stand half a chance at helping out a fellow motorist...or be self-reliant when it's me that's broke down (because it happens when you drive $200 cars).
The cell phone and a credit card don't even need mentioning (so I don't know why I just did).
