Is the Suzuki still on the lot?
If your Suzuki is still on the lot, I suggest that you go to Suzuki with a copy of your VIN number (should be able to get this information from your copy of the Suzuki title. If you no longer have this information, you can request it from your Loan company since you are still paying for it. You need to then go to Suzuki and get them to make you a copy of the Vehicle Key.
Once you have a copy of the Vehicle Key, since you are still paying for the car (bring a copy of a recent canceled check for your loan payment on the car, also bring a copy of the title for the car (since you are still paying for it you still OWN the car). I would then contact your local AAA or another towing company, or contact a Reposessor, and have them go to Bremen Chevrolet and repossess your car from them. If they ask what you think you are doing, tell them since they are in posession of a stolen car, that it is within your rights as the vehicle's TRUE owner to take your property back, and show them copies of the title with you still being sole owner of the car, also with a canceled check for your payment.
You also should call your local police station to have a police escort for when you go to get your property back from the Dealership.
You are WELL WITHIN YOUR RIGHTS to do this as YOU STILL OWN THE CAR!!!!! Go get it back, and let the Chevy Dealership deal with it.
Once you have your car back, you can then go about having the police report of your car being stolen removed from the Vehicle in question, or go about having the vehicle being re-inspected and then get a "Clean title" re-issued, and then you can either keep the vehicle and have it re-insured as a "Clean Title" vehicle, or sell it outright to someone through the local newspaper, or through AutoTrader.com.
Good luck and keep us posted on how things go.
