A variety of cars. My parents cars of course including an Oldsmobile. I guess it's way past the statute of limitations, but a few times in a rental car even though I'm pretty sure the rentals terms didn't allow it. If one was under 18 when getting a DL in California, there was a required drivers ed class as well as a minimum 6 hours of a behind the wheel driver training class. I took the free drivers ed class as my high school, but our high school's waiting list for the free driver training slots were long. We all knew the car though - a Dodge Aries K. My parents paid something like $100 for a private driver training class which was done in a Ford Escort. Don't remember that much other than the horn was actuated by pressing in stalk on the left. One time my instructor wanted to honk at another driver and reached over to honk.
I barely missed passing my first driving test and had to take it again. And my parents forgot it was my test day and I had to call a friend and I took the test in his car.
Some have mentioned learning how to drive a stick. I learned how to do it on a few test drives, which involved quite a bit of stalling. So I bought my car and the salesman took to me to a place to practice for an hour before I sent him back to the dealership and did my best to drive home. I kept on stalling for a whole month until I got it. Still - It wasn't that bad - an import car with a light clutch and five synchronized forward gears. I remember seeing a few Ford Model A's thinking there's no way I'd be able to drive one without killing the transmission. I guess I could learn how to double clutch.
