what i think is the best way to win the gran turismo world championship is:
Step 1: go to a dealer and buy a mazda MX5/Miata/Roadster, it doesnt matter which one.
Step 2: Tune your mazda in any ways you like so it is faster than any other mazda of that kind.
Step 3: go to b spec and start the NR-A Roadster Cup which appears at lvl 6 or 7.
Step 4: join the race and let the driver win the race for you* (*Note, the driver will eventually overtake the cars even if you not have selected the overtake button, in the beginning he will not become first immediatly, so dont freak out.
Step 5: if you have tuned your mazda good enough, you now have won the cup, and the prize car is a Mazda Furai Concept, you will need that car
Step 6: Collect the furai and compete in the GTWC, dont modify your mazda, just race
Step 7: the furai has an amazing acceleration and a top speed of 299kmh* (*note: unmodified) so it isnt going to be a problem overtaking the cars, it wasnt a problem for me.
Drive as good as you can, but watch out, any contact with grass, gravel, sand, or anything and the furai will get out of balance, but easy to recover.
Win the 5 races and then, you'll get your prize: the car that you have been waiting for:
*drums sound*
THE BUGATTI VEYRON!!!
Step 8: collect your veyron and have fun.
i hope my ''way of beating the GTWC'' has been helful to one of you guys
greet!
