Bled and adjusted the brakes, did several touch-ups to the paintwork, adjusted the accelerator linkage to hit maximum with the pedal stopped against the floor, and took GP 8920 for a short drive up and down our street.
Still chasing a charging - or rather, lack thereof - problem and rough running issues, but the vehicle is pretty much completed, at least within my limited capabilities and budget. Not concourse standard, but I'm reasonably happy with the result.
