I'm limited to just 5-Stars!
I'm limited to just 5-Stars! Our family had an exceptional experience at GMC Liberty all due to the service and expertise of Anthony Sanders. We were looking for the coveted 2025 Yukon Denali AT4 (hot ticket item). He knew our needs and was an open, honest, and most importantly a non invasive salesman. This has been our best automotive purchase experience and we couldn't recommend anyone more highly.

We have purchased several vehicles from Tamer at Liberty GMC. He is an amazing salesperson and we continue to go back as he provides us with the best experience. He is a knowledgeable, friendly and no pressure person. I would definitely reach out to him for all your automobile needs. Thenl dealership also has the best finance department we have dealt with by far. Would recommend Tamer and Liberty GMC to anyone in the market for a vehicle.

excellent buying experience
Great no pressure place to buy a used card. Anthony was excellent to deal with and very straight forward. I wouldn't hesitate to buy from Munich Motors again in the future. I completely forgot 6 cd's in the car I traded in, and Anthony texted my to let me know they found them in the stereo. Thanks a bunch for an easy purchase!

2007 Acura TL
I purchased a 2007 Acura TL sight unseen, I don't think I'll ever take that risk again. Mechanically great, visually not so great. I was caught off guard that the car was delivered too quickly. It would be nice if somebody gave me a heads up. I had to leave work just so I can meet the delivery driver. I just want to express my frustration though. I thought the car was going to be detailed before it got shipped to me. I was hoping that the car would be nice and clean when I show it to my son. Also, it wasn't disclosed to me that there were cracks in the windshield. On the plus side, the price was fair, the transaction as a whole was painless. It was a pleasure to deal with this dealership. I just wished the car was delivered cleaner. Now I will have a reason to bust out the Harly's Carnuba wax. and the leather conditioners. The car is fine so far, no pulling on the freeway, it's faster than heck, braking and handling are awesome. Plenty of tread on the Michelin tires, the Carfax was clean, 1 owner, no wrecks, extremely low mileage for the year, and the timing belt was changed twice already. Either the old couple that traded the car in were fanatics about the maintenance, or the Acura Dealership in Peoria was ripping them off. I do see Jeeps in my area with Larry H Miller plates driving around here. So I know he is selling/delivering cars here in Nor-Cal, which is cool to see. The dealerships here in Marin are absolute crooks.

Outstanding service.
Outstanding service. Worked with Erik for my first oil change in Service. He was super fast, got to the point, gave me accurate time frame for completion and communicated with updates while I was waiting. Also, Robert with customer service was awesome and even offered and bought me a star bucks coffee while I was waiting. Probably best dealership in country.

Outstanding sales an service
What can we say when in less than 72 hours we bought FIVE cars from this staff from X6, M3 limited edition, M240i, a year old AMG C 63S convertible, new X3 an looking at a 8 series. I have read other reviews, people remember if you want near perfect buy new or understand buying a car is like going to the doctor your needs can be matched only by your expectations an what is possible.
