Yes. not sure if I’m a car counts at all, but my ex wife and I had sex many many times in my suburban when dating and our van when married.
She and I had sex while camping all the time, Usually in a tent or alone in the woods. However. One night, in a campground, she was drinking and went into the tent, and apparently took off her swimsuit bottoms(She was wearing a long dress, which she always did camping) came back out and straddled me on my chair. I honestly thought she was playing around until she reached down, and pulled my cock out and sat down on it. Her dress covered everything, but it was obvious what was happening. We also had sex on our back porch all the time.
