Midnight Club: Los Angeles

While this sounds like the final achievement of the game, it isn't. In order to challenge the City Champ, you must complete a majority of the game. That means completling all 4 tournaments (one from each region of the city), completing the matches of each city, and completing the wager and pinkslip matches for each region.

It *does* take a while to get to this point, but it is essentially the end of the game's story line. After you unlock the oppotunity to challenge the city champ, you have to beat him in the best of 3 races. He will be driving a suped-up (not DUB) Mercedes Benz S600 which is pretty crappy at accellerating.

As long as you pick the fastest car that you are completely comfortable with, he won't be a problem.

Since he doesn't care what kind of vehicle you choose, you can always race in a motorcycle. The Kawasaki Ninja is a good choice because it is very cheap, and very very fast. After buying it, test it out to see how well you can control it. If you are somewhat comfortable, consider buying the upgraded parts, starting with the bottom few which upgrade your handling capabilities. One of the buttons you will use the most while driving a bike is the A Button. When hitting this button, do not let go of the accellerator or else you will not get the effect. Just approach a really sharp corner at full speed and as soon as you feel the turn is too sharp hold down the A Button until it puts you in the right direction.

Using this bike, you can kick his ass no problem. I beat him first try with over a minute of space between me and him at the end of the first race.

In order to be able to face Booke, you must complete a majority of the story missions. After being at a certain amount of completion, Booke will call you to go to the Standard Hotel. During the cutscene, you will be informed that Booke has three minions for you to beat in a best of 3 series. They are the District Champions Tommy (Downtown; Miura), Leon (Hills; Murcielago) and Laticia (Santa Monica/Beaches; Gallardo).

After beating the District Champions in their Best of 3 series, you will be called back by Booke and must go to the Standard Hotel to talk to him. After the cutscene, you will face him in a best of three series. He will be driving a Mercedes-Benz S 600 (non-DUB variant), which is a Group 4, B-Class Luxury car that has slow acceleration and low handling due to it's heavy weight.

Any vehicle can be used against him, with the Lamborghini Murcielago Roadster DUB Edition being the best choice for this race, as it is very fast and has great handling, and is easily obtainable due to being won from the Downtown DUB Tournament, which is a hard difficulty tournament that rewards the said car for free after winning the tournament.

Any Group 3 or higher vehicle can beat him due to the S600's stats, even most of the higher class tuners, or muscle cars, which can add 2 wins towards the vehicle type champs.
