"i buy cars that make me happy and will be fun to drive. All I'm looking for is what is the best can I can afford to enjoy driving for the money I can spend....gas mileage, I don't really even look at..."
Just because you don't doesn't mean all of us don't.
Gas mileage was one of my top criteria for choosing a car. I bought a car that advertised 27 mpg city, 37 highway, combined 30 mpg. I get around 32 mpg combined, or 35 when I am driving to maximize gas mileage. Overall, I have dropped my gas expenditures 100 dollars per month (roughly) for a car that was under $14,000.
So yes, many people like me do use it as a criterion for their car purchase.
