I don't do any towing or racing but i got a V8 because i love the extra torque and proven engine. My dad has V6 limited, i don't see big difference in gas between our cars maybe 10-15$ a month difference but that's nothing compared to the extra torque u get with V8. i drive mostly in the city...
i have v8 4x4. I drive mostly in the city.
I get 15mpg :p . When i drive 50% city, 50% highway :driving: , the mileage goes up to 17mpg. Well, i did not expect any other results from a v8 4x4 car. I still love it. :)
