I recently bought a used 2001 SL1 with auto. So far, I am getting 35-36 MPG in northern michigan which at this time due to cold tends to degrade mileage a bit. So on the gas thing, I am very happy. But this thing is noisy. Nothing seriously bad as in 'danger master robinson' but compared to my '91 ranger v6 or my mothers '91 lumina or a 2003 Tarus I rented, it sounds a bit busy up front. It has been too long since I had a '86 Escort to remember what it sounded like. Are SL1's a bit low on sound proofing? Thanks, Wes
