Not boasting.. I understand what you're saying but when you join a race on commute/route 68 and every one has fully upgraded Adder's it was a bit frustrating as I was only getting 2/3k a race.
I got a reward of $1000 for being a good sport once haha
Now on three seperate ocassions I've had
1) 2 days
2) 4 days
3) I'm currently on 8 days (got 5/4 days left
