Jimmy, you forget a step.
See, every person has 1 ass:
1 person= 1 ass
And that Jeep can seat 2 people:
1 Jeep=> 2 person
So, that leads too:
1 Jeep=> 2 asses
Now, enters your work:
1 Jeep=> (1/2)ass
1 Jeep=2*(1/2)asses*2 of everything
And this concludes in:
That Jeep=2 asses.
While your math is correct and not far off, that factor of 2 is really required to comprehend the horribleness of this Jeep.
