50mpg is absolutely stunning mileage. You must drive slower than my 85 year old mother.I would love to see what kind of MPG I could get from a Civic hybrid if I could borrow one for a few weeks because I’m already able to average 50 MPG in my 2.0L Civic over long periods of time (I recently averaged that over a a few weeks and 1000 miles of my regular driving) That being said even if it got me 70 MPG, it’s still more financially smart for me to stick with my current Civic for many years to come, it hasn’t cost me anything in repairs since I bought it three years ago.
