Red Tailed Beast - Completed last stage no credit

Same here, on iPad Pro 11”. Completed all the requirements 5 times over a period of 3 days, was never able to complete the event. Now it’s too late to pay 150 GC to skip the event and win the car. 

Same here. Android

I would add to this that after many attempts, I did succeed and complete the event, but I was not awarded the car.  

I have upgraded Audi red tail and pagani utopia to level 3. Both series stopped me completing and winning. I have spent all my gold and $r to get these I saved up for a long time and the game has taken all my money and gold, ea what are you doing ? Do you want us to stop playing ?

The utopia challenge I got to asked me to complete the Bugatti circuit in less and 1:36 and come 2nd. I completed in less than 1:30 and never better than 5th.  I feel cheated

I have the same problem with the Nismo Gt LM. I finished it 3 times and it's not allowing me progress to the next stage. I could see if spending 10 gold pieces would let me bypass it I guess.
