See you did need a lot of money

Earn yourself a lot of money by doing tournements over and over again then do up your cars the best they can possible get done up. I've used this method and i've completed it 5 times already and on the verge of completing it again.

When you start the game you will be supplied with a sports car keep selling it to rake in the money but you'll still have that car you sold

In Hong Kong and other places you can go through trees.

You can do this on other levels too.
