A 1970 Cadillac Eldorado with a 500 cubic Inch, 8.2 liter, V-8 engine with 400 horsepower. That was the largest engine sold in those days and the car got about 8-10 miles per gallon going downhill. It was about 5200 pounds in weight but due to the very high engine torque, it could do 0 to 60 mph in about 10 seconds which was amazing for that time. Along with its cousins, the Buick Riviera and Oldsmobile Toronado, it was front wheel drive. This model was also the last one with no pollution equipment.
