The back seat and passenger seat are $1 options ... The drag radials and skinnies are part of a trunk installed package...
Wrong
The base car comes with only one seat. Note that the passenger and rear seat (which weigh 113 lbs) are $1 options, along with the radio. Air Conditioning is standard as it is used to cool the intake charge for that maximum launch.
Drag radials are standard. The front skinnies and the race gas ECU are part of the optional "prestage kit" that you can get at the dealer with your Demon.
Of course you don't get 100 octane gas at the dealer, but you don't get 89, 91 or 93 there either. If you don't have 100 octane available, the Demon will make 808 hp and 717 ft-lbs, good enough for 9.9 second quarter miles. Still faster than pretty much anything out there.
