I have had experiences at both Martin and Star. Star was extremely rude to me, the salesman took my keys and was refusing to give them back. I ended up yelling in the showroom because of this. Finally I got my keys back. The "deal" they were making me was way out of my price range and I said forget it. I told them what I wanted and all they said they could do for me was sell me a brand new car at some crazy interest rate. After getting my keys back, I left. Later went to Martin Nissan and received much better service. I ended up getting my 06 S from them (this was about 2 years ago). They never held my keys to my trade, never gave me any BS. I knew what I wanted and wasn't going to listen to anything else. And I got what I wanted with no problems. And yes, they do give free oil changes for the time you have the car.

So I guess it just all depends who you deal with. I don't know
