What losers ... Dealers suck! But,
First of all, If you are shopping for a car and you know that you want a MP3 or something sorta like that, then do your homework first. Know what you are buying and what you want ... The Mp3's sold so fast, you would not find a brand new one anywhere anymore. When I bought my car I knew more about the Mp3 then the sales guy ... no hidden lies. I knew what I wanted and what I was getting.
Second of all, if the dealer pulled one over on you, just for the simple fact that they were sketchy with you, I would give them hell. Trust me, the last thing that you want is your dealer to feel like they can walk all over you. That's the problem these days ... you have to be a prick and make a scene just to get your service done the right way. It's like pulling teeth just to get warranty work done at some dealers. JEEZ.
