I sold my old mercedes which was plagued by problems for my '63 stepside, and drive it daily.
I updated all the wiring with a painless wiring kit, rebuilt the carburetor, upgraded to HEI ignition with new plugs and wires, added a brake booster, and installed the T5 trans. Still has manual steering, the 230 motor, drum brakes, and 3.73 rear. It's a great daily driver! Not the fastest thing on the road, but not the slowest either. It drives great and I live in a a large suburban area with tons of traffic.
It still has a long way to go cosmetically, but mechanically it's pretty solid.
