Mine was GT1. I was 5 at the time I played it (I'm 13 now) and because of that I didn't really do anything, because I didn't know how to play the game. My second one was GT3, and I knew how to play the game at the time, but because the game didn't have autosave, I kept doing the first 6 tracks in Arcade mode over and over again. And the third and last GT game I have is GT4. This was the game I wasn't just good at, but great at. It's by far my most played GT game, and becuase it's the best game, beating it's successors by a long shot. I couldn't play these for a while, because I didn't have a PS2 to HDMI connector but now I have one, and I can now replay these great games.
