Actually came back for a 3rd time today to purchase a Tiguan we had been looking at. Everything with the salesman Andy was fine until we found out that it actually wasn't VW Certified (it's under the pre-owned certified section of the website too). Well, this wasn't a deal breaker. Andy was nice enough to continue working to try and make something work. He ended up getting the manager (I believe his name was Michael) to come talk with us. All they would do was knock $200 off the certification so we would need to pay $800 to get it certified. Well, after trying to negotiate with him and being told their car is below KBB, they can't lose money on it, and my trade in they would definitely lose money on it (even after showing me the KBB fair price on my trade in was $2,200 more than what was offered to me). Still, this wasn't the straw that broke the camel's back. It was when Michael decided to pick up his papers while we were talking and say "thank you for coming in, have a nice day." This is the point where we decided to leave. I felt bad for Andy as we were going to purchase still, but a rude manager just means I'm going to deal with rudeness every time I go for service.
And for the future, might want to fix your website listings. It's illegal under to consumer protection of unfair trade regulations to advertise and say false information on a vehicle.
