ALWAYS read the Owners Manual for the vehicle being considered for use as a toad!
ALWAYS!
It is the ONLY real source for information about the towability of the vehicle.
However, it is also true that people HAVE towed vehicles that are not considered towable by the manufacturer. They are willing to take the chance that the transmission will not self destruct due to lack of lubrication.
In truth, ANY vehicle, with ANY transmission, CAN be flat towed, IF the owner is willing to pay the price in transmission repairs or replacement. The destruction of the transmission may take place in 100 to 500 miles, or it may last for thousands of miles. There is simply no way to tell!
Vehicles I know to be towable:
Subaru AWD, maanual transmission (automatic transmissions NOT towable)
Almost any Jeep (there are exceptions, read the Owners Manual for instructions)
Almost any 4X4 that has a Neutral position in the transfer case (again, there are exceptions, read...)
Volkswagen original Beetle, Karmann Ghia, and Thing
Good luck in your search.
