Gran Turismo 5 - Historic Race Car - Deep Forest Raceway (A-Spec) - Gold

Warning: Countach LP400 '74 is way underpowered and hard to control compared with those race cars, this is high difficulty race; if you want to win easily, please use the B-Spec prize car - Toyota 7 Race Car '70, which isn't easy to get either if you don't have powerful race car for Like The Wind event.

I heard this strategy quite a while ago from GTPlanet.net, today I tested it and finally got the Expert Series trophy and Lv.17 car ticket.
So here it is:
1) Max out your Lamborghini Countach LP400 '74, buy Racing Soft tyres and Aero Dynamic parts; if you don't have the car, go back to gold the Lamborghini Exclusive event in Professional Series. (do NOT upgrade the 20,000cr. Chassis Reinforcement!!)
2) When entered the race, make sure no one of below listed cars are in 1st and 2nd place, even better if they're out of top 4 places, otherwise re-enter the event - Chaparral 2D and 2J Race Car, Ferrari 330 P4 Race Car, Toyota 7 Race Car.
3) Make your way to the front as fast as possible and keep it.
4) Block the faster cars behind you all the time, but don't push too hard.
5) The 5th lap (last lap) is vital for victory, absolutely no mistake. (I got lucky as you can see in the video, but don't bet on that to happen!!)
6) My car's settings are listed at the bottom of the description for your reference.
