I think the thing looks like an SR71. Perhaps "Blackbird R8D"? (R=rotary 8=wheels D=deluxe) Or "BR8D" for short, complete with its own pun.
Or, to take one of the audience response lines from Rocky Horror way back in the day: They shouted "tight as a vise and twice as nice" anytime someone mentioned Janet. So, to go with the "twice as nice" notion, you could simply call the car "Janet".
I think all of the Darth Vader and Knight Rider stuff (while extremely appropriate) is way overdone.
