I will just throw this out there, but when you go to junkyards, walk the imports too. Some of them have very interesting ideas used in their design that you will not be exposed to if all you do is look at domestics. Look at the brakes, suspension, interiors, etc. Many times, imports are junked with things like upgraded speakers, etc. that can be bought for little money and used to improve your car. Also look at the brakes and suspension- especially on the larger cars like BMW's and Lexii. German cars many times have very heavy duty cooling systems with pieces like oil coolers, fans and radiators that could be adapted to a G body.
