This dealership is getting worse! I come in for my oil changes everytime. But this time is different I just had brand new tires put on my car on 12/2, im here on 12/4 for the oil change the guy checking my car in tried selling the highest package for tire rotation and balance on my car...... he told me there is significant wear and tear on the tires. I told him no there is not they are brand new. He then questioned me on them. It is something new everytime I go in.... it has 30,000 miles on it and serviced properly.
