basically, you either complete a face off, complete a pursuit, get all golds on the training and crash events, and you can also unlock some cars by completing some of the custom series championship events.
all cars and all burnout tower
yes you freak
play through the game
To unlock cars on the Sims 2, you'll need Sims 2 Nightlife.
you have to need the cheat engine to unlock new tracks on burnout 3
Well there are some cars that you get by entering a code in the "Under the Hood" section. These unlock sponsor cars which are just copies of other cars in the game except with a skin with a sponsor on it. Depending on where you live you may only be able to get some of these cars. Check the Cheats section for more details and the codes. There is one car that you can unlock online called the Carbon Uberschall 8. To get it you must complete 2 sets of freeburn challenges. So for example completing all of the 2 and 3 player freeburn challenges counts as 2 complete sets. Timed challenges do not count towards this. There are 5 other carbon cars that you unlock for completing certain things. Smashing all of the billboards will unlock a carbon car. This is the same for gate smashes, super jumps, time road rules and showtime road rules.

Most cars can't.
Burnout paradise is a free-roam game, and is the only free roam game in the burnout series. Its very different, and has many more things to do, like find shortcuts, drive throughs, and to unlock new cars you must find them in the city and shut them down, so all in all, it is a good game, and there are good multiplayer challenges, events and DLC.
Play until you Win

You need to complete one of the custom series champiosnship events, I can't remember which one, though.
