I'm still holding back buying the BD7 2015 I don't see much of a difference between 2014/2015... my BD7 2014 is dialed last weekend race after not touching and not racing my car in 8 months. I qualified 2nd on our expert 17.5 class after shaking the rust off my throttle finger from racing off-road and got comfortable driving on-road again I took the lead and never look back this is against guys running the Tamiya 419 and awesomatix.
