With an old truck/car like this, there will allways be something going wrong. It really depends on what your wanting. But, in all honesty, if you have the time and a bit of skill, fixing up an older car/truck is actualy cheeper in the long run than buying a new one. Specific concerns with the b2s would be the amount of plastic used in the things. THe plastic ends up falling apart after a while, and your going to find yourself replacing most of it eventualy. Spec the stuff in the egine compartment, and anything on the outside of the truck. I have seen a lot of b2s with ignission issues, having taken apart the ignition switch I think I figured out why, the plastic rots, and it basicly breaks apart inside. With mine, I am actualy planing to switch to a dash board ignition switch for starting it. Stick it somewhere nicely hidden away and no one will be taking my truck, cause thay could never get it started! No matter what thay did to the switch on the wheel.
THe worst thing with starting a project car/truck, you have to deal with all the crap everyone else has done to it. Some of it can be quite unplesent and quite difacult to repair. Still, once you got it running nice, Might take a while, it should stay in the shape you maintain it in, and you should be able to easily keep ahead of issues.
