Do i have a lemon?

What is the name of your state? Minnesota

i recently brought a 2003 Nissan Maxima. They gave me all the info i needed on the car but stupid me i didnt take the time to look into the details. When i brought the car from the dealership it had 27,567 miles on it...finally today, June 14, i decide to look at the carfax papers that they gave me. I looked at the odometer record and it said it had 28,438 miles on the car in January 11, 2004. Thats about 1k miles off.

So my question is what can i do? can i return the car back? should i just accept that fact that whoever was reading the odometer for carfax read it wrong, if thats what they tell me? Should i keep the car?

As of right now i dont feel like keeping the car anymore not that i dont like it, it is a great car actually but just the thought of someone messing with the odometer makes me mad and not want my car.....please someone help!!!!!!!!!!! BTW i brought the car 2 weeks ago exactly
