When you start off Evolution and do the Saleen Qualification, you should unlock a Hummer H2. Go straight to your garage and sell the H2 for $67500 so you have no cars again. Now, go back to the Championships and do the Saleen Qualification again. Repeat as much as you want.

By driving into various items on the roadside you can fill your boost bar much fast than usual, things like boxes, phone booths, and road signs are all great objects to drive through and gain more on the bar.
