We bought a Cadillac with them and our sales treated us good except they won't offer you any discount. While we were doing the financial stuffs the guy mentioned about the upgrade warranty and he added it on our car without asking us first. Didnt even mentioned how much it would cost (it was $2800) but my husband said just let it go so I let it go (eye roll). A week later we brought another car in to be service (oil change, tire rotation). We made an appointment for 11:15am, 12:30pm and our car is still sitting at the same spot. Also, when we came in at the appointment time there was a lady that came in AFTER us and she got served first, she didnt even have an appointment. Why do I need to make an appointment if I'll have to wait for an hour+ to get served? Its ridiculous but hey what can you do, its the keys.
