I got this idea from a radio show "Garage Logic" over in Minnesota back when I lived there and I thought it would be cool to do here.
Basically your C.I. or Cylinder Index is the total of cylinders in all of the cars/trucks/cycles/lawnmowers/etc that you personally own. No company vehicles or whatever. As long as you own it(or you & the bank) and it has a piston. Rotaries don't count either.
A good C.I. should be equal to your age.
For example, when I was 25, I owned 2 vans, 2 small cars, and a Kawasaki (V8 x 2, + I4 x 2, + 1cyl) = 25 CI.
Now my CI is 6. My age is 34 so hmmm, not good.
Whats yours?
