Arcade Mode: Unlock all 8 tracks and 4 new car manufactures + High Resolution Mode:

To unlock the four new tracks, the four new car manufacturers, and Hi. Res. Mode in the Arcade Mode takes lots of work and practice.    Process: Take 1st place in each track with a C- class car, a B- class car, and A- class car on easy.  That unlocks all the four new tracks.  Then repeat the process in the four new tracks.  That unlocks four new car manufacturers.   They are Toyota, The New Dodge, TVR, and Subaru.
Repeat the process for all eight tracks on normal.  Then go to Bonus Items and you'll see that you'll be able to choose to watch a little video with the credits of the game.    Now, for the last time repeat the process for all tracks on difficult.   Then select Bonus Items and you'll see a link"Hi Res Mode."  If you select this mode you'll see that it is almost the same as racing a regular race.   After you select your car you'll see that there is only 3 tracks to choose from.   Track # 4 and #7 from the regular racing mode, and one new track;  It is similar to the other two tracks.  In this awsome High Resolution Mode, you'll be racing in a Time-Trial,   the animation will be unbelievably a lot faster, and best of all your car goes super fast.

My opinion on the best cars in the Arcade Mode
