First dangerous indicator is that most of these reviews are either one star or 5. I am not saying the 5 stars are fake, but it makes me suspicious.
From my personal experience, do not trust these people. They LIE!!! OK. Maybe I shouldn't be shocked that car dealers lie, but to have blatant boldfaced advertisement that is an undeniable lie shows how overtly shady Chapman Mazda is. When I purchased my car there in 2011, I was given a $10 oil change for the life of the vehicle card. By life of the vehicle they must have meant 2 years. They discontinued the offer and their explanation was that they could change an offer anytime they want. I understand changing an offer to new buyers, but changing it on people who purchased on a "life of the vehicle" offer is just being dishonest. The service manager told me on the phone that they are offering an oil change at a price that nobody else is matching.....$30???? Wow! I have never heard of an oil change for less than $31...another blatant boldfaced LIE. These people are just so dishonest. If they are willing to advertise so falsely, imaging what other lies they are willing to tell just to make a couple extra bucks.
