Ooooh, my turn, my turn, my turn /ubbthreads/images/graemlins/crazy.gif
Quality stuff. I have literally been injured by cheap tools. Not to mention the inevitable destruction of nuts and bolt heads by C*#@)%$y tools.
Start with a test light. The sort that has an alligator clip lead and a pointy awl-like probe with a light bulb in the handle.
Next get a quality flat bladed screwdriver and phillips screwdriver in a "medium" size (both blade and length).
Purchase a set of open end and a set of box-end wrenches (spanners). I suggest one of each instead of a set of Combos because I seem to always guess the wrong size (and the alternate is right there in your hand /ubbthreads/images/graemlins/grin.gif) or you need another wrench to grab the other end of the hopelessly spinning bolt/nut/whatever.
Needle nose pliers.
Diagonal cutters.
Wire strip/crimp pliers.
Oil filter wrench (most useful is the pliers-type).
Oil catch basin... rubbermaid wash basin works well.
3/8-inch drive breaker bar, 3-inch extension and a spark plug socket. Notice I didn't say to get a whole set.
Heavy duty jack stands (2 minimum).
Hydraulic floor jack.
Large curved jaw Vice-Grip... the real deal.
You should be able to accomplish great mayhem with these. Later, as you notice what sort of tasks you seem to be doing, you can acquire additional items. The first thing I wanted was a small set of nut drivers (socket attached to a scew driver like handle) They have been most handy for small nuts/bolts. If you do, get the one-piece units as the interchangable ones tend to come apart in awkward moments.
