A friend just went through this with a Dodge Neon. He had a $40 service charge in dispute with SouthTrust bank, but was still able to get them to clear the title when he finished the payments. 120 (or was it 180?) days later, they sent someone to get the car. He ended-up paying almost $500 in fees (for the tow and for storage) to get the car back, and the tow driver ripped the front bumper cover off. He also never got back the items that were in the car when the bank had it taken, including an expensive car seat and stroller. When the local towing company had his car in storage, the local police said there was nothing they could do. I called in a favor with a local magistrate, and he said the bank was within their rights to take the car over a disputed charge, even though it was owned free and clear. He also said that no matter what happened, taking the car could not be criminal act by the bank. It's civil.
Astrogoth, I suggest hiding the car if you think they're going to come for it. Got a garage? In some states, they can legally break into the garage to get the car. Make it disappear. Trade cars with a friend or relative that has a garage. If you think their demand for $1600 is too strong to ignore now, wait until they have your car. Also, take everything of value out of it. Finally, contact your insurance company about this problem. My friend had his policy dropped without warning when his car was taken. He drove around for almost three months later without insurance coverage without knowing it. Thankfully, he wasn't in an accident.z
