87 = 1.49
93 = 1.79

I drive 16k mi a year.

A S/C will get on average 5 percent lower mpg (20 mpg SE/ 19 mpg S/C). Doing the math...

SE yearly gas cost is .149 X 16,000 = $2,384

S/C yearly gas cost is 16,000 X .05 = 800 so then you would do 16,000 + 800 = 16,800 X .179 = $3007.20

Driving 16k miles a year, considering on average the S/C got 1 mpg less than the SE, and living in the area of Maryland which I do, I save $623.20 a year on gas. That translates to $52.00 a month. Seems like a pretty big deal to me just to get some extra horses which I don't really benefit from (towing capacity of a SE is the same as an S/C).
