|~Samantha's Unique Spoilers~|
Getting 3 Unique Spoilers at Same Time: Duotek, Katana and Dual GT. You mustn't use a Hatchback Car for this cool glitch to work. First get a non-hatchback car, go to race 77 (Time Trial, Samantha's Big Tease), beat the race to get to reward screen. Don't choose Dual GT or Duotek, as they have both Saloon and Hatchback versions and thus won't get you additional Spoilers. Instead always choose the Katana, save the game and exit Underground mode. At Main Menu go check "Customize Your Ride" section, choose a Hatchback Car and see Dual GT will be available! Now choose a Saloon Car you will see not only Katana is available, but the Saloon version of Dual GT will be available, Too! This will happen almost everytime, but if you have extra cash and want to make sure it happens 100%, choose Katana at Underground mode, go to "Customize Car" section in Underground mode, now trade-in for a Hatchback, and trade back the Saloon car again, you will see this happening!! As result, you will see only 2 kinds of Unique Spoilers in Underground mode (Katana for Saloon and Dual GT for Hatchbacks), but at Main Menu you can find 3 kinds of Unique Spoiler available (Katana & Dual GT for saloon and Dual GT for hatchbacks). Note: due to the glitch, non-hatchback version of Dual GT will stay with your ride's color.
|~The Money Glitch:~|
Play Underground Mode until you get the Skyline. Make sure you have enough money to change to a VW Golf. Buy a VW Golf then put all your Performance Parts on it. Once you have done that, trade it to an S2000 and take all the parts off it. Once you have done that trade to a Skyline (it will cost 3000), then trade back to a VW Golf for a gain of about $11000 (not bad huh?), you can continue to do this for as long as you like.
|~20" Rims All The Time~|
Use Rims that normally wouldn't fit, certain Cars can only fit so big of a Rim. For example, the Miata can only fit 17's, but if you get a car like the Skyline put 20's (Unique Or Level 3 Rims Only) on it and trade it in for the Miata. The Miata will now have the 20's that the Skyline had on. Don't install any other Rims on your new Car because the Rims will go back to the original maximum size allowed. So select the Rims you really like and put them on the Skyline then do the trade. But you can still paint the Rims anyway you like afterwards. Also the visual effect is very KEWL...
