When did my family go from one car to two?

My earliest recollection of life was living in a 1960's era neighborhood in Dearborn Heights, Michigan. It was a small house on Bedford that had a double lot perfect for playing baseball in the backyard... just don't hit the ball to far or you have to go get it. The house had a small driveway that was perfect for one car... which at that point my parents had a single vehicle. That car was a gray Ford Fairmont. When my dad would go to work he didn't take the car, no he rode his bike. I remember him peddling off down the street on his green ten speed. Then for some reason during the next couple of years we moved around a bit... I don't really know but I think we still had a single gray Fairmont. I can remember very clearly when we transitioned from one car to two. It was roughly 3rd grade for me at Wareing Elementary in Taylor, Michigan. We got the news sitting in the sun room of the house that my parents were divorcing. That is the point my dad moved out and bought Volkswagen Scirocco. From that point forward I had in my mind that it was normal for families to have two cars. Which if it the norm for parents get divorced than it is a necessity to have two cars. I don't want to get divorced and I don't want two cars. I want one car and two bicycles.
