Extra boost at start of race
Immediately after starting the race, honk the horn twice by pressing [R] while holding the brakes ([B]). If done correctly, you should receive an extra boost.
Best "Truck"
This vehicle looks more like a chicken than a truck and all four of the stats are full, so this could be VERY useful! But you need to beat ALL, and I mean ALL of the records from Rookie to Proffesional on the 30 tracks So if you want it ASAP, you need to beat the game.
