My freshman year of high school a buddy had one. A burgundy SA22 to be exact and at the time it was just awesome. In fact, when it was running, we would let all 135 oil thirsty ponies have at it in the back parking lot of our high school which made for some awesome memories.
In Japan the RX7 isn't nearly as rare, but it is still the stuff of legend. On any given day at Daikoku Futo PA you're likely to see at least one. And the one you see will likely best any of the stateside examples you've seen. Here's a whole row of them for you to enjoy.
