I've put together a small album of clearly wrong car specs and descriptions: http://imgur.com/a/VNUDA Each of those images shows issues like a turbo car being shown as naturally aspirated (and vice versa), incorrect engines as well as massive power discrepancies in the same class. In addition, we really need car specs in the vehicle selection screens actually in-game. Thank You.
The data on the left of each car is accurate as far as I can tell. The description text underneath the car picture is indeed outdated.
