That's really low mileage. I used to get those numbers in an auto Accord, city driving like I stole it. Have you modded the unit between the seat and the pedals yet?
I go to Lowes/Home Desperate 3x/wk. I've thought about the vinyl roll flooring as aeromod material before. Plastic is great because its weatherproof, and I see you get that cold white stuff on the ground.
