Hint - Median Exploitation
If you have 2 long roads beside each other, with a thin grass median in between the roads, you can use the instant challenges, and the computer player will follow the road, while you can just drive over the grass and finish in about 10 seconds.
Hint - N00Bs Starting Cash
The easiest way to make money early in the game are the "Delivery Missions". Most of the early ones start out at $80,000. And if you can deliver the car in perfect condition you get a big bonus. Plus there is no time limit on these missions so you can take as long as you want to get from point A to point B. I made enough money from 6 - 8 delivery missions to buy a second house and 4 more cars and I still have around $200,000 to play with.
The added benefit to these missions is to force you to drive more and learn the various qualities of each road and track on the island. Experience with the game is no substitute for a huge bank balance!

Hint - N00b Cash #2
There is a challenge at the South East corner of the island, which requires you to top 140 miles per hour on a winding road.
When the challenge starts, simply spin the car round (after making sure you pass the start line), and head to the road behind you. There's no finish line, so by turning left or right you're on a nice straight road where you can hit 140 in about 10 to 15 seconds, then just hit the A button to finish.
You make $10k for doing this, in less than 30 seconds, then can simply repeat to make some quick easy cash!

Hint - Key Location Detection
Even if you didn't unlock things yet, you can zoom into the map as far as it will go and look for black squares. Places such as clothing shops, vehicle showfloors, and many other places show up as a black square. Just set your marker and go check it out!
Hint - Who Wants To Exploit A Millionaire?
When you reach Expert level a new timed race will show up called "The Millionaires Challenge" which is a $1,000,000 race... The best way to win this race is to buy a MV Agusta motorcycle, and upgrade it to level 3. Then you can race the race with only a type "A" car, or motorcycle. You can do the race as many times that you wish. I earn about $30,000,000 a day on there, and now have around $150,000,000 and 12 houses with 56 cars. It is a 60 minute race and I finish it in about 49 minutes... So have fun making a lot of money!
Hint - N00B Cash #3
In the bottom right hand section of the island is a race called "170mph in heavy traffic". You can do this race over and over and get $15,000 every time.
When you become a champion, there is another race called "180mph in heavy traffic" in the middle of the map; the reward is $70,000 and again you can do this as many times as you want.
If you're driving a stage 3 Enzo, this race takes about 15 seconds, which means you'll have $1 million in about 10 minutes, so dont waste your time doing the millionaire's challenge anymore.

Hint - NOOB Cash #4
If you are a champion and own at Ford GT with a level 3 tune-up, you can enter the Ford "Ford day" Race to the left of the Honolulu Airport.
The Race gives you $75'000 every time you win, and the race only takes about a minute. So just restart every time you cross the finishline, and in about 10 minutes will have made $750'000.
