FARMING GUIDANCE with ANY POWERFUL CARS!!! - NFS: No Limits (TU 065)
Trick is, failing at 4th race several time to buy nitro and ecu parts. Then upgrade the Jesko till you pass or meet the PR wall.
With this method, farming is gonna be easier. If you upgrade the Jesko with any Top Speed and Acceleration parts, you have more losing time to slow down the car, and higher chance you're gonna totalled / wrecked your car later.
It also works with any SE that the enemies car slower than yours.
