Worst place to take your car for services!!!! I took my nissan Sentra that was still under warranty to do the services. Rafael (supervisor) Gave me really bad attitude he even asked me for how many years I been working on this country because Supposedly thats the way auto nation works and I had to pay the mechanic , My car already had an inspection in nissan and I showed him the paper in which it said what the car needed to be fixed , he even told me to not make that face when I was told that I had to pay 130 , soo disrespectful I even told him that I didn't worked on a dealer so he had to explained it to me and he started to scream so I left.Wont ever go there again! Really bad customer services The guy thinks he owns the dealership!
