-The best car to start with is the Mazda MX5. It has a great top speed, moderate acceleration and awesome handling. The car is also one of the best cars to proceed in the game. Only the Mazda RX7 and Nissan Skyline are better.
-For the drag part, use a Honda S2000. If you have the perfect shift and the extreme performances, you will be about three or more seconds ahead of the rest. For drifting, try a Mazda RX-7 because its a good rear wheel drive car. For the rest, try using a Civic, Skyline, Eclipse, and the Acuras. They have fast response, but not to the point where you will hit the wall and sometimes spin out.
-The best handling car is the Mazda MX-5, the best car in acceleration is the Acura RSX, and the best top speed car is the Nissan Skyline R34J. The Volkswagon Golf GTi or the Mitsubishi Lancer are not recommended starters in Underground mode.
-The best car to select when beginning a new game is probably the Neon (until you get farther into the game, some tracks get very difficult).
-When starting, use a Neon. It is not as good as the Miata, but it does not slide out of control as easily. Later, change to a Subaru Impreza. It revs hard at the start of a drag race and it has great control.
