Yeah, what Tom said about the TOD (Torque On Demand) system. It is considered an all wheel drive system.

One other thing to look at (and this isn't a deal breaker) is the front bumper on the VX. It is a tube that is hidden behind the front cladding and you can easily see it (if it's there) by looking into the front wheel well in front of the front tire. The bumpers are notorious for completely rotting away. Many people know that there's are gone and drive on, some probably don't know that it's missing and continue to drive. It does nothing for the performance of the VX but would provide some (VERY minimal) front end protection in a crash.

Keep the questions coming.
