Bought a used car from here and had a nice experience. The dealer is really open aired inside and feels welcoming. Sales desk surround the exterior wall so it feels really open inside and you can see the new hotness BMW offers. When I walked in I wasn't approached right away and after a minute or two someone asked if I needed help. The sales woman was nice and got right what I wanted to see and didn't waste time, which I liked. We took the car for a test drive and she encouraged me to test the brakes and test the car out a bit. She was able to answer most of my questions pertaining to the tech. features of the car and gave me additional info about the car and the dealer. No pressure and was a nice experience.
We returned to the dealer and we talked some more and I said I was still looking and I would be in touch. I ended up buying the car from here as they DO NOT have any hidden fees. No "nitro" fees or window etching fees to help hike the price of the vehicle up. Not all dealers do it but I was dealing with 5 other dealers and 3 of them did have some other fees that raised the price of the car.
While talking to the finance guy, he told me that I would have to keep the auto load for 6 months before paying it off or I would suffer a penalty, he couldn't tell me how much it was though. I get a letter from the bank 2 weeks after I purchase the car and speak with a rep over the phone from Wells Fargo and she informed me that there are NO penalties for paying off early and the reason dealers may tell customers to hold the loan for a certain time frame is so the dealer can make a "bonus" or credit from the bank. I thought the finance guy was on my side till I heard about this. I understand dealers need to make money but to lie to a customer face is pretty ballsy and not something I like.
I was looking forward to bringing my car here to be serviced but with the finance person misinforming me this may change.
