Is there a bug in this? I am 100% certain I have driven all 30 original cars more than once in time trial mode setting a lap time on my favourite track. Is there a list of cars required, I have even gone through classes and variations of cars and still stuck on 29/30
I was wondering the same... I'm at 27, not sure which cars I drove to be honest. But I'm sure that driving the Pumas didn't make any change. Maybe this is normal as those cars were not expected when the achievement was created? But I think other people already reported being stuck at 28 or 29.
