The plan should work. It worked well for me, even though I started when there were only 18 or so days left. Ready to Rumble gave me 5000 exp every time I raced him when I was at level 1. So, 20 races at 5k exp a pop equals 100,000 exp. Be sure to work every now and then as you will need gas and when you level up, you will make more money, so you will need to make sure you have sufficiant calanders.
