1976 300D automatic transmission (no turbo)!!!

This car is totally Stock.
Up to 70 MPH, my daughter gets a solid 21 city - 25 highway MPG, even when treating it like a sports car.

Above 70 MPH the MPG seems to fall, roughly 1.65 MPG per 5 MPH.

Example: MPG 18 when driving 90 MPH, and the engine is NOT happy.
