For over a year I was driving a really fun 79 El Camino that I knew got terrible gas milage and leaked lots of oil. The best I could do on a nice relaxed week of driving was maybe 9 mpg if I didn’t accelerate hard and never went above 50. I actually tried it for a week.
Then I got a Subaru with a weird transmission and a little engine that didn’t require a quart of oil a day.
Saving money is nice.
