Working with Brittany was awesome..she is very knowledgeable and professional Would recommend that you ask for her if you are shopping for a car
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Miss information on servive
Very upset that when I bought my truck was never told I had to bye a oil treatment after 15000 miles witch cost me 89. Dollars on my next oil change to keep my oil changes for life I was not told that when I bought my truck I think that’s crap not happy about that and don’t intend on paying for the oil treatment.
I have had to of these before and I drive the xxxx
Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

Thank you Manny for a great experience!! We will be back when we need our next vehicle!
Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

They were very helpful and willing to go the extra mile. I have no complaints. Mike
Unbelievable towing capacity.
The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

I recently had an exceptional car shopping experience at
I recently had an exceptional car shopping experience at Auto Boutique. From the moment I walked through the door, the staff was incredibly responsive, addressing all my queries with patience and professionalism. They were genuinely helpful, guiding me through the process without any pressure, ensuring I felt informed about my choices. The politeness of everyone at Auto Boutique was particularly noteworthy; they made me feel valued and respected throughout my visit. I have not yet found a car that perfectly matched my needs but left with a positive impression of what customer service should be. Highly recommended for anyone looking for a smooth and pleasant car buying journey.
Capable truck with the right options
Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

I will never buy a GMC from anywhere else. The dealership and people are real and not fake flashy like others. I drive further to get my vehicle serviced there over Jerry Seiner because of the quality, timeliness and communication from the staff.

Came here for a really great looking Ford Explorer, the salesman Will was great and had paperwork for the recent suspension components the dealership replaced after finding some issue during their safety inspection. Ended up going home with the rig. I absolutely love it!

Thank you Sales Manager Hector
I found Hector Gonzalez, a Sales Manager, at One Toyota of Oakland to be one of the most professional sales managers I have met while I have searched for a used Japanese compact or sedan car for my price range at various brand name dealerships and secondary used car dealers for the past few weeks. He was extremely helpful in addressing all my concerns about purchasing a used vehicle from the One Toyota dealership, went through the quote thoroughly without hassle, was excellent in keeping in contact with me throughout the process, and made me aware of additional warranties and issues that other dealerships never offered to help allay some of my concerns when purchasing a used vehicle. I would highly recommend asking for Hector Gonzales if you are purchasing a vehicle from their lot for his excellent customer service and professional demeanor.

EASY TRANSACTION, GOOD TRUCK
I bought a F350 online thru Cory. I bought it unseen, just pictures. I had the truck picked up by a friend and brought to New Hampshire. Truck is in very good shape, and I got it at a great price. Cory was very easy to deal with. Next time I need a truck, I will call him.

Dorsch (Ron & Dallas) were a pleasure to deal with when
Dorsch (Ron & Dallas) were a pleasure to deal with when it came to purchasing my vehicle. I never purchased a used car from an out of state dealer that was so far from me. The process can be scary but they provided me with various pictures, videos, and all the information to formulate my decision. I flew in from New York and they arranged to have me picked up from the airport. The negotiation process was pretty simple as well. I drove the car back over 1,000 miles without a hiccup. Great dealer to deal with; 1 would recommend them to anyone.
