First of all, I would recommend visiting the local car shop, even if you managed to win Sonny's Volkswagen Golf. You should do that every time you defeat someone from the Black List, not only to buy a new car, but to compare their current performance bars.
Audi TT (#1) is one of the most enjoyable cars to steer. Nevertheless, I wouldn't recommend buying it, because you would have to spend a lot of money to get a hold of the best performance upgrades. Furthermore, you only have to access to several parts at the moment, so the TT couldn't use all of its potential. You might consider buying this car in the future, though.
Audi A3 (#2) is a little bit faster than the TT, but it handles worse. It's also not that good when it comes to acceleration. I would recommend sticking to the Volkswagen Golf. Audi A3 could be used as a second car, but at the moment you don't have enough funds to afford two different cars with the best possible upgrades.
You should consider selling Chevrolet Cobalt SS, that is if you picked up this car earlier. You can do it from your garage window, but I would recommend going to the part shop first and taking off the performance upgrades. You should receive some cash from that. Selling a tuned car is not wise, because you will lose a lot of money that way. As for the moment, I would recommend spending all money on better parts for the acquired Volkswagen Golf. Concentrate on performance, not visual upgrades (Sonny took care of them).
A guy named Taz is next on your list. Before you'll compete with him you will have to take care of a number of different challenges. Like I said before, you don't have to complete them all. Concentrate on those races and milestones that seem to be less complicated. That way you will be able to advance on the list much faster. You should also remember that you may restart your favourite challenges in order to get extra money or Bounty points.
Taz wants you to do following things:
1) Races won: 4
2) Milestones completed: 3
3) Total number of points: 50000+.
1. Circuit - Petersburg
You start off on a freeway. Bear in mind that you may cut through the next corners, because driving on the grass doesn't make you any slower (#1). Use this to your advantage, so you may extend your lead even more. After reaching the bigger turn use the left shortcut in order to pass through this area safely (#2). Remember this spot, because you will have to use it regularly. You might want to turn on the Speedbreaker feature for a few seconds in order to stay on the path.
After you reach the second part of the freeway use the arrows to help you navigate to your destination. You will have to choose the shorter LEFT path (#1). Remember to use the nitro button from time to time.
2. Sprint - Hwy 99 & State
This race is a rather simple one... that is if you know the track itself. A couple of more difficult corners await you just after the start. I would recommend slowing down before taking the first corner from this group (#1). Be sure to choose the wider path, so you won't hit any barrels along the way. Use the grass in order to cut through the right corner located below the huge building (#2). Don't worry, you won't lose too much speed by doing this.
3. Sprint - Clubhouse & Hollis
Be sure to cut through the first corner located on your left (#1). You mustn't slow too much. Avoid the surrounding walls at all costs. Don't worry about the opponents. You should be able to catch up to them quickly. Watch out for the 90-degree turn. You will have to use your brakes aggressively. Just as before, concentrate on staying off the barriers surrounding the track. Police forces will join the race shortly. You will have to avoid their attacks.
4. Tollbooth - Skyview & Campus
This is your first tollbooth race, so it would be best to explain its rules. Don't worry, these types of events are VERY easy to complete. The objective of the race is to reach a couple of checkpoints in a designated time. Once you reach a checkpoint the overall time is being extended. After the start pick the left route (#1). You will have to watch out for other cars and trucks, but it will help you to improve your final time. Be sure to use your nitro often. After you reach the tunnel get back to the right track. You shouldn't have any problems with getting to the next gates (#2). Furthermore, the game gives a lot of time to do that.
This time you will have to complete three police challenges. If you won't succeed in earning enough Bounty points try picking up pursuits on your own.
1. Infractions Challenge (6000 points)
This challenge is a very easy one. You will receive infractions by doing all sorts of things - destroying the neighbourhood, speeding, hitting police cars, driving outside the roadway... Be sure to outrun the pursuit when you're done with it.
2. Bounty (6000 points)
You will have to gather at least 1000 points during a single pursuit. It's a very simple task. You'll just have to hit the police cars from time to time. You will be rewarded for each hit. Furthermore, you might be able to connect the hits in order to receive additional points. You should complete this challenge in less than a minute.
3. Photo Ticket (4500 points)
If you don't have enough points you might want to consider choosing a "well-paid" milestone. Otherwise, this one will do just fine. You will have to exceed 90 MPH (150 KM/H) in order to complete this challenge. It shouldn't be a problem, especially since you have a fast Golf.
Both races aren't that challenging as you might have expected. You will need to complete two Sprints, so you won't have to do any laps. Nevertheless, it would be wise to spend some money on the performance upgrades before you throw a challenge.
1. Sprint - Stadium & Hwy 99
The first race has some tight corners. You'll probably have some problems with cornering them properly. The first corner is located near the start line (#1). A second one will appear just after the long straight (#2). You will have to use your brakes in order to make a successful turns. Remember to use your nitro often. Taz might speed up near the finish line. You have to remember that and be ready for any of his attacks.
2. Sprint - Rosewood & State
The second race is even less complicated than the first one, however you should be careful while going through faster corners (#1). If you don't measure them properly you might end up on the brick wall or even outside the track itself. Nevertheless, winning this race shouldn't become much of a problem (#2). Remember to use your nitro while getting closer to the finish line.
Just as before, you will have to pick two cards. You should try and locate the Lexus IS 300 that belonged to Taz, however even if you will be able to win it, I'd recommend selling the vehicle in order to get extra money.
