Yeah, the Miata enduro is pretty much drive around conservatively with T2 tires, and you'll win, cause everyone else pits in a bunch. I happened to ahve the fastest stock Miata when I did it, but I won by like.... 3 laps or something, so it could easily be done with a lesser one. But yeah, its fun too, cause its not painfully hard to win, not an oval track (I hate the test course, I just stick the car in max gear, tape the accelerator down, and let it drive its self :/ ) so I recommend that one as your first.
