Is it bad I want to go back to a cheaper car?

I'm 21 and I bought a new car this spring. It's a 2011 Ford Taurus. I bought it because I had an 09 that was developing weird and expensive problems. I used to have an early 90s Taurus and I loved it. I was going to start driving my 03 Town Car again but discovered problems with the frame. I traded in the 09 for the 2011. The price was $11,000. It's financed. I put $3,000 down and my interest is around 19% so that makes my payments around $270 a month at 75 months. My insurance is paid up until next month. I make the payments on time every month. I went back to college. I have a part time job but, I'm thinking buying this car over a $5000 older car wasn't the best choice. I can't afford a lot of the things I need so I make it work with what I have. I've never missed or been late on a payment and usually pay $10-$20 extra. Nobody helps me pay it. I can't sell it because I owe more than it's worth. I'm not going to stop making payments because it'll ruin my credit. I run a side business (mobile car detailing) and I work. So I NEED a vehicle (and a fairly big one). What should I do here? I have 70 payments left. I'd rather be able to just put the money towards things I need. I love the car and can kind of afford it but I kind of want to go back to a payment free or smaller payment car. What should I do?

Added (1). If anything, I'll just keep making the payments. I plan to transfer after community college and I don't know if I'll be able to make the payments at that point as I intend on going far away. My insurance is only $100 a month. But would be cheaper with an older car.

You put your self in a situation you're not going to get out of without at least penalties to your credit. Unless you find some idiot that wants to pay more than this F-word is worth to sell it to that has the money to pay it in full so you can pay the financing off your choices are keeping it, trading it in (you're unlikely to get it's value let alone what you owe on it so you will then have 2 car payments for a while) for something cheaper, or killing your credit by forfeiting it and doing a voluntary repossession by giving it back to the dealer.

Another option is that you may have a slight chance that the dealer you bought it from will buy it back from you at it's value and somehow work the numbers of the remaining balance you owe to make something cheaper for you work.

I knew this story was going to be something like this when I read that you keep getting yourself F-words.
