i would actually say the million dollars is about right by the time you pay for welding ,machining,fabrication and electrical engineering classes, tools and equipment along with materials, parts, and electrical components..plus you still need to put gas in the thing....:toilet:
seriously though a total moderate build is going to run somewhere around 4~5~6k depending on what you go with and what you do.
1.3k for lift and suspension parts, bushings ,end links ect
1 k for tires and rims
1.5 bumper and winch
1k for batteries,lights,wiring,switches,radio's ect
1 k for other modifications uca's,sleeping box, stereo, ect ect
bare bones can be done for about 2k if you have tools and the skills to fabricate your own stuff.
