posting some info I found...
“As is” means that you are buying the car exactly as it is on that day. The dealer will not be responsible for any problem with the car. If the car breaks down, you will still have to make the payments. There is no 3-day return rule unless the contract specifically says so. When you buy a car “as is,” you are taking a big risk. It is better to buy a car with a good warranty.
the vast majority of used cars sold by individuals will be sold "as is" with no warranty and no recourse should a major problem arise with the car. However, if you take some reasonable precautions by having a used car checked out by a qualified mechanic, and you are willing to take somewhat of a chance on a car, buying a car through a private party may be the best choice for you.
After you test drive it, you should take a few minutes to walk around, crawl under, and pop the hood of the car. Check to see if there is any dripping fluid, smoke billowing from the exhaust system, or any build up of dirt and grime on and around the engine.If you are testing a car for sale by an individual, it is also good practice to ask to see their file of maintenance records and any receipts of auto parts and repairs. Most people keep many of these records, and if the seller claims not to have any at all, you may want to view the car with a degree of skepticism.
Sorry bro, but it seems like alot of your problems would have been notice and caused some alarm if you had taken a decent test drive. I would imagine that your case would hold much weight in court. While I do agree you got a shitty deal. there were steps to take to keep from getting ripped off.
Also, I looked it up and you have no rights under the lemon law.
