Well, it’s not exactly a trick. What you need to do is save up about 40k and get up to level 5. This shouldn’t take too long at all.
Now buy the Ford Focus RS and move to the amateur league. Enter the clubman competition.
The races are relatively easy and you’ll probably only have the other Focus as a challenge but its not too hard. Win all the races at $4600 a pop and you’ll receive a $14,000 bonus at the end for winning the championship.
This take about 20 minutes all up… not too bad!
