I don't feel guilty at all, maybe once China, Mexico, India and other super emition producing countries like Andorra clean up their act then maybe.
But then all of my familie's cars are pretty clean, my 87 190E is a lot better then many newer cars.

This past weekend I drove to Palm Springs and back, going I got 27 MPG averaging 70MPH and on the way back with four people and luggage I got 26 MPG averaging 75 MPH (hitting 90 a lot) Not fun going 20 over and looking back at a highway patrol car, but the feeling you get once he passes you...
