Way, way over 100. Impossible to even remember all of them. I compulsively buy vehicles and have for 40+ years.
Once in a while, someone will say, "remember the xyz car you used to have?"
"No."
Then, with some extreme prodding, it will come back to me. I've forgotten cars I've owned in the last 5 years. I have a list in a notebook somewhere from about 1986 that filled an entire page. It was a memory exercise. Next to it was a list of every chick who really got to me at that time, it was also an entire page from elementary school through mid-20s.
