My mom had a red over white Chevrolet convertible in the early 60's. An Impala, I guess, it had the wings over the tail lights. The front seat was comfortable to stand up on while mom was driving down the road. The metal dash was a bit hard, but that's the way it was back then.
My sister, who is quite a bit older, had one of the first Camaro's, a 327 auto, IIRC. It was black vinyl top over yellow, like a bumble bee.
I remember my father's '63 ( ? - the model with the jet exhaust tail lights, maybe it was a 65 ) T Bird. It had the steering wheel that slid side to side. It had a really bad habit of backfiring through the carburetor and setting itself on fire. When you're four or five or six years old, that makes an impression on you.
I've owned a few Fords, and a few cars made by companies owned by Ford, but have never been much of a Ford person. I blame it on that T Bird.
edit: My paternal grandmother had a '59 (?) white Pontiac Catalina. She always called it "the Pontiac". She was really proud of that car - owning a Pontiac was a big deal to her. My paternal grandfather was a Mopar man to his last breath. He knew Walter or the Dodge brothers, for all I know. He just shrugged it off the first time they went belly up. When I started college, he had a mild interest in my Honda, and told me I would be lucky if it lasted a couple of years. He missed that by one year. It made it about three.
My maternal grandfather was a Lincoln man, and I the first I remember of his cars was a Continental with the suicide doors. My maternal grandmother did not drive, to the best of my recollection.
This was all from the very early 60's, except for the Camaro. I was seven or eight by then.
