Today, put 180 miles on it going to a junkyard to pick up an '81 Pontiac Bonneville Safari that my buddy is going to use in a demolition derby. Interesting thing about the car, it has a 350 cu in DIESEL in it and all the maintenance records were in the glove box. Not sure if it runs yet or not. No keys so he has to hot-wire it.
While towing (I'll post a pic later), I got 15.9mpg. I was fairly impressed by the mileage.
