How do I know if a car is RWD, FWD, 4WD or FWD before purchasing it?

Solution 1:

There isn't a way to determine what drivetrain your car will have before purchasing it in-game. There are few external resources that provide this information as well, with the NFS Wikia being the only webpage I could find and vastly out-of-date.

Sorry, but it doesn't seem like there are any resources to reconcile this.
