These guys are a bunch of crooks. A buddy of mine bought a used 2003 dodge 3/4 ton 4x4 Cummin 3 months ago. It had aftermarket rims and tires on it and he bought the extended warranty for 1800 bucks. A month ago his transfer case went out, so he took it back to the dealer and they told him they couldnt warranty it because it had aftermarket rims and tires on it, even tho they were on the truck when he bought it. He ended up having to put the transfer case in himself at a cost of 2000. So now he got himself a lawyer and is sewing for the cost of the transfer case and the cost of the extended warranty.
