chrysler capital rainbow car dealer of mccomb, ms overcharged for vehicle. car was only worth 8,000 at sale price...charged me 13,000 mccomb Mississippi

The transaction was not a rip-off because sellers [of any merchandise] are not required to observe or follow market prices. You are suffering from a case of buyer’s remorse and therefore an attorney can do nothing for you.

What are the terms of the written warranty or was this an AS-IS sale?

You wre not "overcharged" for your car.  You were charged exactly what YOU agreed to pay.  If you paid $5000 more than you should than that is because you didn't do your research BEFORE you bought the car.

The reason your balance is still $9,500 is because of a little thing people call "Interest".  Depending on your credit rating you are either paying a low rate or very high rate.  But again the rate you are paying was disclosed to you when you bought the car.  As for being "upside down".  Guess what your "friend" failed to mention.  Cars always loose value, and unless you put a significant amount of money down on the car, you are going to be "upside down" on your loan for a majority of the loan.

As for "already" having problems with your car.   You bought a 2009 car 2 years ago, if it lasted 2 years without major problems you got very lucky.

As for talking to an attorney, you can go ahead and do that.  But they are going to tell you the exact same thing.  So I would suggest that you use that money that you would pay them with and pay additional funds on your car.  Because you aren't getting out of the car loan, and NO judge would even remotely consider giving you your money back which would have in effct given you a free car for 2 years.

By the way since you have a friend who is an old dealer, I would suggest the next time you go to buy a car you take him along.

First of all, it is now Nov 2016 and you want to get your money back on a vehicle you purchased in 2014?  Not going to happen. I don't work for this dealership or any other dealership, but why would they give you your money back? You have no basis to even request your funds to be returned.

If the dealership charged you more than the vehicle was worth, the time to notice was before you signed the purchase agreement.  You would have seen the purchase price right on the first page of the contract.  If it is not what you are willing to pay - then don't sign it. Get up and walk away.  

Next, you are repaying the loan to the lender - not the dealership.  The lender is the one that is out the funds for your purchase.  You have a contract with the lender to repay the loan - whether or not you have the vehicle. There is no provision in the contract that if you have mechanical problems then you don't owe the lender your payments to repay the loan. How do I know? Because the loan repayment terms are totally separate from the vehicle maintenance issues. One has nothing to do with the other. 

By the way, the reason your vehicle loan is "upside down" is because you negotiated a poor purchase price on the original purchase and because of the interest rate on the loan and because you didn't put enough down on the vehicle purchase. All of these contribute toward the loan value being greater than the vehicle value.  All of these things are within your control at the time of purchase.  You are the one that chose the dealership and the lender. Until you understand the proper way to buy a vehicle, the dealer reps will take advantage of you.  Take the time to research the proper method to buy and finance a vehicle. HINT:  do not get your financing through the dealership - get it from a credit union. Also, do not trade in your vehicle as the dealer offering you the trade value has an incentive to make that offer fo your vehicle as low as possible.

Summary:  pay this vehicle off, sell it and the next time research the right way to buy before you ever go looking for another vehicle. You are not entitled to your money back based on your post. Talk to a lawyer, maybe they can talk some sense into you.
