Aaron,
For me, it's not all about how much you saved, it's more about "I did it myself." I've saved thousands pulling my own engines, doing my own brakes, doing my own electrical repairs . . . But, if I had to figure in all the tools, bandaids, fire-fighting equipment (long story), and doctor bills (laying on the wet, cold ground in the middle of the winter might save you a few hundred dollars at your mechanics, but it isn't good for your health :? ) I probably should be driving a brand new SUV.
Guess I watched too many McGuiver episodes when I was a little younger. I'd rather take a beating than pay someone that actually knows what they are doing to fix my vehicle.
