It must include b-spec mileage as well. That's quite disappointing; I'd prefer mine kept separate from that buffoon.
Wow, I just checked mine... 60k miles. I think most of those are B Spec at this point. I've been trying to get to level 40 B spec to finish off that side of the game and concentrate on just A spec stuff. My poor X1 has been doing 24 hour of le mans races for like a week now and I'm barely getting to level 39 tomorrow night.
