Fastest car
The best combination on GT3 for starters is the Toyota Yaris. Buy this car and you should still have quite a bit of credits left.
With these credits go and buy the turbo stage 1 upgrade. This should skyrocket your bhp from 90-100+.
Then once you win all the races in the Sunday Cup, you should win the Toyota Trueno Sprinter car. Sell this off and buy a couple more upgrades.
These upgrades are up to you.
