There are a lot of tools that make your life easier, the best way to take care of your problem is buy a few tools, start working, and buy more tools as you need them! If you start out with a fairly comprehensive set, you can save money.
Pliers, breaker bars, u-joint sockets, extensions, fixed wrenches, small rachets, big rachets, vise grips, screwdrivers, multimeter, wire snips, wire strippers, a few torx, small pry bars.

- European cars you'll need a decent torx set and maybe even some 12 point sockets.
- Old american cars often call for large breaker bars, angle grinders, and impact wrenches.
