That is a good number, it is a three speed automatic heaviest model Opel that was imported. In top tune and driving it like you have a raw egg under your foot it might do 23 MPG. They are somewhat under-powered and with the 3:44 rear you are at about 2500 2600 RPM at that speed. If you do mostly highway driving you might do a little better with a 3:18 rear but 80hp pushing a 2300 lb. car is only going to do so much.
