Start off by visiting one of the nearby car dealers. I should inform you that from now on the game will be unlocking some of the most interesting cars of the Career mode. Sadly, you can't buy all of them. You might have decided to stay with one of the "older" cars, although I'd personally recommend getting rid off most of these vehicles and looking for something new.
Aston Martin DB9 (#1) should be known to those of you who love beautiful cars. Sadly, it's not one of the best cars available in "Most Wanted". DB9 is certainly very quick, especially when you take a look at the acceleration and top speed bars. Sadly, it doesn't handle very well. You will probably notice it while exploring tracks with a lot of difficult corners. This car is also overpriced. Aston Martin is much more expensive than the 911 and it's certainly not any better. Furthermore, you would have to spend a lot of additional cash on performance upgrades.
Porsche 911 Carrera S (#2) is definitely one of the most interesting and useful cars of the Career mode. First of all, this vehicle is vey easy to handle, especially when you compare its abilities to the DB9. Porsche is also a lot cheaper than the Aston Martin. Thanks to that, you will be save up some cash for additional tuning or other purposes.
I'd personally recommend having two different vehicles. Both of them must have all of the unlocked performance upgrades installed. The first car should be used in races with a lot of corners and during police chases, while the other one would show its advantages during Drags and on a long stretches.
In order to pick up Ming's challenge you will have to deal with several races and milestones first. Here's the list of the current requirements:
1) Races won: 7
2) Milestones completed: 4
3) Total number of points: 2300000+.
1. Sprint - West Park & Lyons
You should know that there will be a lot of tracks with long stretches in the following races. Remember that and choose correct races from your garage. Otherwise, the opponents would have left right after the start. Let's concentrate on this challenge for now. At first, you will have to deal with several mild corners. About a half way through you should brake aggressively in order to pass through a tight turn safely (#1). A series of very challenging corners awaits you (#2). Remember to pick your current route wisely, so you won't lose too much speed. Start using nitro near the end. Thanks to that, you should be able to secure your victory.
2. Tollbooth - Interchange & Tunnel
This challenge is a rather easy one, although you will have to avoid police forces along the way. Be sure to cut through most of the upcoming corners. You will be able to use the left shortcut (#1). The toughest corner of this race (#2) will require you to make a sudden right turn. Remember to brake aggressively. Some more corners will be waiting for you here. You don't have to worry about them too much.
3. Sprint - Hwy 201 & Lyons
There are a lot of straight lines on this track, so you have to pick the vehicle carefully. Otherwise, you wouldn't have any chances on winning this race. Remember to use your nitro frequently. After you reach a small junction head on to the path located on your right (#1). The final part of this challenge is by far the most difficult one. Be sure to cut through the wide corner (#2). Don't worry, any of the surrounding objects won't slow you down too much. Keep going STRAIGHT. Don't turn just yet, because you might hit one of the nearby walls. Make a turn AFTER you leave the underground parking. Use the nitro to secure the lead.
4. Tollbooth - Penitentiary
You shouldn't have any major problems with the first part of this race. Watch out for the small jump. After you reach the road located under the freeway slow down a little, so you won't hit any of the surrounding pillars (#1). You should reach the main part of this district within a few seconds. Get ready. There are some fast corners here (#2). If you have a car with decent handling abilities you probably won't notice any problems with this segment of the challenge.
5. Sprint - Bond & Country Club
This is a rather challenging race, although if you're a skilled driver you might complete it without any unscheduled restarts. You will have to get through two difficult corners (#1). They are located near the start line. Be sure to pick a correct path, it would also be wise to use the nitro from time to time. The next corners will appear shortly. You might have some problems with the second one (#2). The final part of this race is less challenging. You will have to deal with several stretches. It all depends on how fast your car really is.
6. Drag - Riverside & Terrace
Just as before, you will have to concentrate on avoiding the city traffic, rather than changing gears or using nitro (#1). You shouldn't have any major problems with this challenge, that is if you memorize all of the city cars.
7. Tollbooth - Hwy 201 & Forest
This is a very easy challenge. Like I've said many times before, most of the success depends on the performance of your current car. At first, you will have to deal with several fast corners. Be careful, because if you're driving at very high speeds you might hit one of the surrounding barriers (#1). You will have to cut through a very difficult turn, located near the end (#2). You might want to use the small shortcut, although this is not necessary.
1. Trade Paint (80000 points)
You should have at least one very powerful car by now. It would be best to use it during these four challenges. Thanks to that, you should earn more points than it is actually required by the driver from the Black List. During this challenge you will have to take care of at least 22 police vehicles. Thankfully, you should score points even for some smaller crashes. You don't have concentrate all of your effort on destroying them (#1).
2. Pursuit Time Challenge (80000 points)
You will have to maintain a successful pursuit for at least seven minutes in order to accomplish this challenge. Thankfully, you shouldn't have any problems with that.
3. Roadblock Challenge (80000 points)
The rules of this challenge haven't change since the last time. You will have to break through or avoid at least ten roadblocks (#1). Remember that you may try hitting some of them again. If you're lucky, you should be able to score another point. Thanks to that, you won't have to look for any other roadblocks and there's a less change of being caught. You should also remember to stay on freeways all the time.
4. Spike Strip Challenge (80000 points)
I guess I don't have to remind you that you should be VERY careful. Even a smallest contact with one of the spikes will result in a mission failure (#1). You should also remember that you won't have to break through police cars in order to score a point. It would be best to stay on the grass.
This time you will have to deal with two difficult challenges - a Circuit race and a Speedtrap run. If you're thinking of taking down Ming without any problems you will have to acquire ALL of the unlocked performance upgrades for your favorite car. The vehicle itself must have a very high top speed. Handling won't be important during both of these races.
1. Circuit - Little Italy
You will come across a very tight turn, located near some mild corners (#1). Try picking a correct route, so you won't lose too much speed. After a long stretch you will have to deal with two other corners (#2). Both of them are rather challenging. Remember to use your brakes earlier than usual, because you will probably be driving at a very high speed. You can't afford slamming into one of the barriers, because Ming will probably use it to take the lead away from you.
There are more tight corners nearby (#1). Thankfully, you should be able to cut through most of them, so you probably won't lose the lead... that is if you don't make any serious mistakes. There's a straight line leading to the finish. You have to use the rest of the nitro. If you're lucky, you will come across a small jump along the way (#2).
2. Speedtrap - North Bay & College
This is one of the most challenging races of the Career mode. The main complication involves Ming's Lamborghini Gallardo. It's a very fast car. You will have to be quick in order win this race (#1). Concentrate all of your efforts on the speed cameras. You don't have to reach the finish line in the first place. It's also very important to use nitro frequently (#2). Watch out for those cameras that have been located near fast corners. Good luck!!
You HAVE TO win Ming's Lamborghini Gallardo. It's one of the fastest and most agile cars of this game. You will be using it for some time. Furthermore, Ming's vehicle has many performance upgrades installed, so you won't have to buy them on your own.
