I'm going to cheat a little bit here. Technically, my
first car was given to me by my father's friend. It was a tan 1987 Subaru GL with a transmission on its way out.
I beat the crap out of that car and so it wasn't long for this world. The first car I actually purchased was what got me into BMW's in the first place...a 1990 BMW 325i (E30):
picture was taken sometime in late 2001, I believe...before smart phones were a thing, hence one of the only photos I have of the car
