A Forza 4 Money Glitch is available in the game and works very similar to the one found in the third title. Basically using this strategy, you can earn upwards of 100,000 Credits in less than 20 minutes!
The glitch is easy to do (some people say it’s not a glitch, and apparently it has yet to be patched and may not be patched, because it is more a tactic than a glitch) but does take some changing of menu options and the like. Things must be set up properly before the glitch will work.
This video fully explains what to do and how to earn quick and easy money in Forza 4!
