Is there an 'unlock all' cheat in Burnout 3?

I am way too lazy to grind for everything and just want everything unlocked.

Is there a cheat for this?

Solution 1:

Here is a cheat to unlock all vehicles. While on the screen to choose your vehicle, type in:

Y, Y, Y, Y, X, Y, Y, Y, X, X, Y, X

to unlock them all.

I found this via searching, although the original source is in French. I don't know if this works, but it is the only cheat I found on the Internet.

For a walkthrough on how to unlock specs in the normal way, here is a guide on IGN (too long to copy content here).
