Not really- the plan for the near future is to simply use it & enjoy it. The steering wheel logo has been replaced with a cobra badge similar to the wheels, the interior light is now LED instead of the OEM glow worm and I've put a replacement stereo in but that's about as far as it goes for now. The only thing other than that was new bushes in the rocking-chair seat.
That being said, if anyone has any bright ideas they'd be willing to share then I'm all ears.
