To me, presentation of a vehicle is everything. Whether its a DD, Garage queen, show car anything. To me, it shows how the vehicle is taken care of. I know that this isnt necessarily true in all cases but if I see a vehicle thats paint is faded, scratched to hell, interior is filthy etc, makes me wonder wat the internals of the engine are like. If you can't take 20mins every now and then to at least wash the car, what would make me think you can take 30mins to at least give it an oil change?
