If you ever watched the movie "Tucker", you might recall the scene where they were scrambling to get the car together before it shambled onto the stage. I imagine the same thing went on with the P5. I suspect there will be weeks of clean-up work before they allow any journalists or other non-employees to drive it.
The P5 is still a LONG way from production. Look closely at the large pictures posted by Autoblog. The body panels are held to the frame by glued-on and tack-welded perforated steel. The radiator has inlet and outlet on the wrong side. No hood latch. Climate control screwed to the dash with visible phillips-head screws. The random hoses and clamps plumbing the engine. Cable ties holding the plug wire boots onto the coils. The list goes on.
Even so, the P5 is a good improvement over the P4. At least this one has the right engine. They did a great job of cleaning up the front suspension, though I'm curious if there will be any more enclosure of the opening. The hood and trunk lid hinges are complicated, not sure they are a good choice for cost containment! Gauges still look dumb, but at least they are in the car. Interesting new third spoke on the bottom of the steering wheel. Don't see any cup holders, but nice to see a real row-your-own shifter in the right spot and three pedals on the floor.
