I fully understand what you are thinking. I got to challenge 43 and could not get through. I tried 15 times and managed to complete the goal (10 knockdowns without knocking) 2 times, accumulating 18 QC. I did not want to spend tokens, because there are not many. I had just bought the Camaro 2016 in the 4300 promotion. I'm ready to be played with the game for all my investment to desperate. There were 12 V8 engines, 14 mid techs and during ¢ 240000, plus the expense with upgrade to max.
