Takes me about 1 hour and 5 minutes in the morning, 1 hour 15 minutes evening. Been doing it for 10 years. I recently retired my '89 Mazda 626 turbo with 300,000 miles and replaced it with my '95 E300D. My Mazda was incredibly reliable, never opened the engine other than scheduled timing belts, original turbo. Electrical gremlins finally did it in.

Just shows to go you that gassers can be long mileage animals as well as diesels. But I love the 24 gallon tank in my 124, and I love the fact that diesel is much cheaper than gas here in MD.

interestingly enough, the Mazda and the E300 get about the same mileage, 30 - 32 MPG.
