How Much Does It Cost To Own A Subaru WRX STI?

I bought my Subaru STI in March of 2014, and sold it 27 months later. I was curious about how much it cost me over the two years, so I did the math, looking at depreciation, fuel, insurance, maintenance, interest, and aftermarket parts. The results are somewhat skewed, as I only had 14,100 miles on the vehicle, and also averaged 23 mpg. I also throw in a comparison with my Integra.
