In illinois is there any law stating when you buy a car from a used car dealer you have certain time to return it/

I appreciate your question. Unfortunately, I am not licinsed to practice in Illinois so I can not advise you on Illinois law. Generally speaking, most states have a Lemon Law but they are meant to apply to manufacturing defects that cannot be fixed after several attempts. This is not the case that you are describing. However, what you describe would fall under basic principles of Breach of Contract - i.e. you were promised something, and you didn't get it. Your problem now is "evidence". Without having the promise to fix the problem with the alarm in writing, it comes down to a he said/she said dispute. Nearly impossible to win. You could get an estimate for the repair and take the dealer to Small Claims on your own. Hopefully, they would agree to fix it before going to court over something they could resolve easily. I highly recommend that you contact an Illinois attorney to get advice specific to Illinois law, and perhaps seek representation if necessary. Good luck.

Generally, the buyer never has the right to cancel a used car sale unless there is something in the sales paperwork that says it. You need to talk to a local Consumer Law attorney who deals with this kind of case. Call your local attorney's Bar Association and ask for a referral to an attorney near you, or you can go to this web site page (http://ohiolemonlaw.com/locate-a-local-attorney.html) for a nation-wide listing of consumer lawyers and find one near you (lawyers don’t pay to get listed here and most of them are members of the only national association for Consumer Law lawyers, NACA.net). Also, for every legal right you have, you only have a limited amount of time to actually file a lawsuit in court or you automatically lose (it's called the statute of limitations), so don't waste your time getting to an attorney and finding out what your rights are.
