I think you should skin it in something like this:
- Use single lug racing wheels..
- As for interior I like the raw metal look with all the welds showing... Show off your skilz.
- Big speedo and tach... but instead of just a redline the tach should say OH ****. The speedo should say ridiclious seed for what ever the top speed is.
- Front and rear independent suspensions.
- GPS navigation... or do you want a copilot with a map?
- Valve covers could say "Improbablility engine"
- Brake pedal should say emegancy use only.
