The entrance is on the east side of it, where it says "S&M Auto Sales". To get the listed reward, you must bring the vehicle in perfect condition.

Go to the Helitours located at the bottom right-hand corner of the middle island. There are five employees wearing orange reflective vests. Start with the person that is furthest away from you. If you start fighting with the first person you see, a second one will come over and double-team you. Each person will last about two counters.

Keep joining and quitting matches until you are the host. Then, set the lap number to one, and start a helicopter race with very few opponents.

Go to the bridge that takes you to the second island and has train tracks under it. Walk along the train tracks towards the second island before you are allowed to cross the bridge. When you are about half way, you should have a six start wanted level. Then, just stand on the train tracks for five minutes to get the achievement. You do not have to worry about the police because they will be on the bridge above you so they cannot shoot, and the helicopters are above you so you have cover from them.

Go to the hospital at the north-west corner of Algonquin. You can also get there by dying in that general area. Get a motorbike. Set a Waypoint at the hospital or just remember the way you came. Drive to the nearby bridge that takes you to the third island. You must not have access to the third island for this trick to work. Slowly reverse backwards over the barricade on the bridge until you get a six start wanted level. Then, drive straight back to the hospital. To the right of the hospital as you are coming back is a little red fence that you can bust through and get onto the elevated train tracks. Wait there for approximately five minutes to get the achievement. No cars can get to you on the train tracks and the helicopters cannot shoot accurately enough to hit you at motorcycle speed.

Attempt to enter one of the locked boroughs early in the game to get an immediate six star wanted level by taking a car on the subway (or elevated train) tracks. This can be done easily near the corner of Grand Boulevard and Leavenworth Ave. in North Bohan near the police station. From Leavenworth, take a left onto Grand, and go up the little hill. When you reach the crest of the hill, look to your left to find a very short wall above a subway tunnel. Drive a car over that short wall, then drive underground toward North Algonquin. When you have a six star wanted level, stop your car and remain there for five minutes to get the achievement.

After the middle island is unlocked, steal a helicopter from the helitour site in the southeast corner. Fly over any other area you have not yet unlocked to automatically get a six star wanted level. Fly off the map in any direction, and stay in the air. The police helicopters will only chase you so far. After five minutes, you will get the achievement.

Go to the airport runway in a fast car (Infernus, Super GT, police cruiser, etc.). There are small yellow ramps scattered in the grass by the runway. Locate one, drive back a good distance, then at full speed hit the ramp so that only half your car actually hits the ramp. You should get enough spins to get the achievement.

Go on the Algonquin Bridge that connects Dukes to Algonquin. Find the part where the lanes split at the bridge when going westbound. At the split is a small ramp. Hit that ramp at high speed to make your car roll over several times. Try to land in the lower area for more room to roll over.

Get a four star wanted level, then start a mission to get the achievement.

Get on the airport runway with a car, then get out. This will instantly give you a four star wanted level. Then, run or drive to the end of the runway to get the achievement.

Start picking off cops one by one. Your wanted level will rise as more of them are killed. After you get a four star wanted level, get in a vehicle, and drive into the subway tunnel. Once you leave the flashing wanted circle and your wanted level disappears, you will get the achievement.

Get a motorbike, and go to Francis International Airport. Go to one end of the runway, start to accelerate, and do a wheelie by pressing Left Analog-stick Down (with Xbox 360 controller) for 500 feet to get the achievement. The runway works best because you have a very long distance where you can drive perfectly straight without worrying about vehicles pulling out in front of you.
