Just going through the events to earn some cash. Up to last race on B class. The one race I need to complete requires me to buy a Nissan GTR 07, I go to dealership to buy it but it says I can't buy that car, I have completed and passed all the other races. Now what? Also for some reason it seems like the cars have way more grip in event mode than on time trial/arcade? Why is that, something I need to turn off? I can take the highspeed ring reverse in 1.10 in event mode, but in time trial there's way less grip. For example I can take T1 at around 170kph in event mode when I hit the apex right, but in time trial that speed makes me loose grip and under-steer into the guardrails so I have to slow down to about 127kph? Why is there such a difference?
