Forza Motorsport 4

this achievement should come naturally if you are aiming for 'legend'

things start picking up a bit from season 5 onwards, with faster races and more aggresive opponents.

try as much as posible to use cars you are familiar with as this will help you no end. If you have trouble with some races try adjusting the dificulty on the pre-race screen. If that doesnt help then make a note of which cars are giving you grief and try using one of them. i found the alfa romeo brera very useful, especially for b class races.

throughout career mode i also chose to knock out affinity level 50 and ferrari collecter, so every time i was offered a ferrari as a free car i took it, and used ferraris wherever possible as the f50 is excellent for S class races.

finally, if a race is really getting too much dont forget, you dont need to win the race in order to progress, just finish it. You can also hire a driver to help you out should you wish. this will be the 5th option on the 'race start' screen
