Gran Turismo 2

Easy Start:
This game is very different than GT, you don't win Cups anymore, you have to race tracks one by one. Also, most of the races are limited to a certain HP. The first races you should take are the Sunday Cup and the Clubman Cup. Buy a used R32 Skyline and tune it enough to have a lot of HP. Race all of the races and keep gaining money.

The Ultimate Driving Machines:
After you have established at least 4 million, buy the Suzuki Escudo Pikes Peak Version which sells for 2,000,000. This car is monstrously powerful and quite easy to handle at high speeds. If you drive well enough, you can race any race and defeat all your opponents. This car will whip the competition in the GT World Cup so have fun.

How to get a viper GTS-R:
Start game and win enough to get a car with 591 horsepower and then go to endurance races and go to Apricot Hill 200km. You must have internation B licence and win 1st place and you will receive $500,000 and the viper GTR.

Car wash glitch:
There is a mistake at the part where you wash your car. When you go wash your car, it says it costs 5,000 credits to wash once. But it's really costing you only 50 credits.

Mad Cash for real:
First go buy the Suzuki Escudo Pikes Peak Version if you haven't already bought. Then go to the GT all stars Red Rock Valley race. When you win the race you get 50,000 credits.the car you get is a TVR speed 1 which is worth 500,000 keep on repeating and win some big bucks.

Quick cash:
First get your international B license. Then buy an Audi S4 and max it out. Make sure you only have the stage 3 turbo equipped. The stage 3 turbo gives your car 534hp. Then go to the GT Euro League. All of these races are a 591hp limitation so you will be alright. There are three races and each one gives you 10000 for first. Since the Audi is 4wd you should have no trouble winning. As you win each one you recieve a race vehicle ie: Zexel Skyline. Each vehicle is worth 250,000 credits when sold. Each race is three laps but if you win all three and sell the cars, you can make 780,000 credits in one sitting!
