To be honest, I didnt really enjoy this game what so ever. The whole situation about upgrade level is something I question now. A car with an upgrade level of 449 beats my car that has an upgrade level of 502, yet my car that is now upgrade level 509 cant beat a car with upgrade level 513, however, I beat a lvl 520 car, but still get beaten by an opponent using the same car I have, but the only difference is they have their upgrade level at 449. Can you please explain to me how is that possible?
