I've had many interesting (and some not so interesting) cars over the years, but these were my favorites (beating out a couple of BMW M cars, Supra turbo, etc.)
First Porsche was an 81 911SC
Second was a 94 C4 Widebody in Midnight Blue no less (they used the last of the turbo bodies on these cars to use up the shells as they switched production to the 993)
The MINI was the car I turned into a track day toy and probably the most fun car I've owned (though I think I spent more on the upgrades than I did on the car, and people always laughed at my brakes, but I always told them it was more important to be able to stop than go!). It also holds a place in my heart since I a) taught both kids to drive and drive a manual in that car and b) it was each of their "first cars".
