Hints
Buying cars
When you want to buy a car but you do not have enough money, do not wait until you win enough for the purchase. You will not be able to get enough money to buy the good cars until the next era. For example, the Moby Dick car is $450,000 on the market in the 70s, but will be sold broken for over $2,000,000 on the used menu. The 365s in the 50's sell for between $11,000 to $13,000, but will be priced broken for over $100,000. When you are short of cash, buy the used cars, fix them up, then sell them for more. Collect money until you have enough to buy a new car.
More money
Buy the used cars and fix them up. Put them back on the market and you will get more money than you would if you sold a new car. If you want even more money for the old cars, keep them until the next era and they will be worth $60,000.
Repairing cars
Purchase a used car and choose an "Overall" repair. When completed, the value of your car will be higher than the purchase price and the cost of the repairs. Sell the car, purchase another used car and repeat as needed.
Losing the police in "Factory Driver"
You will get various kinds of missions when playing "Factory Driver". Some of the missions involved getting Porsche cars to customers in time and without scratches. Use the following trick to avoid the police and other cars that may block you in a chase. When you driving and see the police keep the "horn" held until police lose you. This works most of the time.
Try all cars and tracks
Simply enter multi-player mode and select the "Peer To Peer" option, but race alone. You will be able to select any car on any track.
Get your car a rally skin
It works only with 996 turbo 00, Boxter 97, or the 911 Carrera RS. All you have to do is open the folder (need for speed.../game data/car data/) and change the file names of the cars. There are two types of cars each 996, 996 f, boxter, boxter f, and carrera rs. Now you have to rename them the ordinary 996 file to 996f and 996f to 996 and so on.
