Vehicle Illegally Repossessed?

Hi, US Marine here..

I financed a vehicle in California, where I'm stationed through a bank based out of Florida back in 2006. Late 2007 I couldn't afford to keep insurance on my vehicle so I parked it in my barracks parking lot, and the registration had also expired. After my car sat there for about 2 weeks the MP's had my vehicle towed to a local auto shop where the bank was called, had a representative come and allowed them to sell my vehicle. Now here's the fishy part. They didn't tell me they were selling my vehicle, they did not report my vehicle as being repossessed, and it did not show up on my credit report that it was repossessed. I am still making payments to this day and have never missed a payment or been late on a payment. They are also still reporting to the credit agencies that I am making payments. They also did not reimburse me the amount that the vehicle was sold for on my loan balance. Now, I only have 4 or 5 months left of payments. What is going to happen when it's paid off? Are they going to give me the pink slip to a car they sold? Is what they did illegal?
