Spares..what do you carry ?

A lot depends on the vehicle and what you use if for. On a daily go-to-work vehicle, you want to carry things to get you off the side of the road. A good spare, dist cap, rotor, ballast resistor, ign. module, fuel filter, along with the necessary tools to install them. For a car you're taking on a long trip I would just add a complete tool box. Unless you're driving to outer Mongolia, you can get whatever else you need at an auto parts store.
