just purchased used car was totally repainted in 09 how can I find out Y? on 2004 Hyundai Sonata

B4 I bought it I took it to an AAA garage for their pre-purchase inspection. They told me a few things that needed to be done. I had some concerns about the front end suspension and steering and asked them to check for frame damage or any evidence of an accident. None were reported by them. Now I find out that the entire car had been repainted by MAACO in 09. Car fax comes up clean for accidents. Any one know where else I can go to find out why this car was repainted??
