My son was deployed to Iraq in late February 2008. He was living with a roommate. When he left, he left his car at the roommates house on a public street. It seemed there was a problem with the clutch on the car. The roommate was/is wanting to buy the car. My son told the roommate that he would pay 1/2 of the cost of the new clutch. The roommate had the car towed to a garage. Ended up being the transmission. I called them and explaind the situation and told them not to do anything until I had contact with my son and see what he wanted to do since he would have to pay for it and the fact that is was on limited income. Well, they replaced the transmission and want $4500.00. In todays mail came a Certified Letter stating that a Mechanics Lien has been placed on the car and he has 30 days or basically he will lose it. He still owes $20,000.00 on the car. I am his Power of Attorney and they still did not listen to what I said and when asked why they performed the work, they said because the roommate sighed the work order to perform the work. This event is happening in Texas. With him being in the service, can they do this? What is his right?
