I will be coming back.
This was my first expericene shopping for cars and I was a little nervous, the sales people at Auto City made me feel welcome and did not overwhelm me with sales pitches. Frank was kind and helpful and I appriecated that. I did not purchase a car that day but because of the treatment I recieved will be going back there in the near future.
2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Hats off to Annie the GSM.
Hats off to Annie the GSM. I came in after 5 pm for a test drive, mind you they close at 7 pm. My test drive was a 23 Outlander SEL with dealer plates. I drove it alone and was sold on it. Annie ran the numbers after 6 pm and qualified me with an APR way below what another dealership had offered, even after a hard inquiry. She worked hard for that sale and had me out the door a few minutes after closing time. No pressure, up front about pricing, warranty and add-ons. All in all I would definitely recommend El Cajon Mitsubishi as they are a small, local, no pressure, honest dealership. 5 stars.

Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

High Quality Buying Experience
Brian was knowledge and made time from his other responsibilities to work with us. The car we called about was ready and waiting for us when we arrived. This was our first (and likely not last) CarMax experience.
Worth the wait to finally have it
We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

Buying a car was so easy and transparent with Encinitas
Buying a car was so easy and transparent with Encinitas Ford. Loved working with Larry (sales) and Dan (finance). Such a better experience than I had with another dealership.
Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

What an amazing experience!
What an amazing experience! I had the pleasure to have John Khalil as my sales agent, who happens to not only be a welcoming and zealous sales agent at CarMax of Oceanside, CA, but also a very talented painting artist!! He had great compassion for my autistic son and made sure he was always comfortable during the efficient waiting process by offering him a cute CarMax car toy, a CarMax coloring book and crayons. He went above and beyond when complex situations came about during the bank’s verification process. The determination he had to push my situation through with his persistent diligence as I watched him communicate with high professionalism and positivity as a team with his colleagues/finance management team was remarkable!!!! Thank you, CarMax of Oceanside, CA!! You all are an amazing TEAM!! I’m so happy with my car!!!
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Best Experience Ever!
No complaints, all praise and compliments! I admire carmax business model, and them having a no negotiation rule is a beautiful thing. Ray was my consultant and we sold our 2012 forte to buy an suv. Message me if you have any questions and I will answer them.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Happy First Time Cuatomer
From the moment we walked up, we felt comfortable. No pushy car sales man. These cars sell themselves. Jesse was amazing. The process was quick. They offered me more for my trade in than anyone else AND I got a great deal on my new Discovery!
Great vehicle. Love it!
Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

Straight to the point!! I can dig it!!
I talked to the guys there about a car on the lot. They explained to me how the process of purchased worked on their lot therefore I was up to speed on the what I was buying and how I was going to do that. Once we made the purchase Fred even through some goodies in to save me some money down the road on upgrades. I'll definitely continue doing business here!!
Looked at more expensive truck with less options, bought
Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Highly recommended. A+++ on all accounts
Highly recommended. A+++ on all accounts. I came early in the morning, I was the 1st customer and within 2 minutes I was approached by a very kind and professional sales representative David. I was checking out if they have specific cars and features that I wanted like leather seats, Hybrid, etc,. He was very knowledgeable, friendly, professional and really listened to my needs. Non aggressive, good energy, easy going. If you want a good sales rep ask for David. Customer Service was excellent. By the way, I am female who drove many different cars so I was aware what I like, like and pros and cons of different features which often correlates directly with price itself. I had a budget that I was willing to spend and maximum number of miles on a car. David completely understood my needs. No pressure whatsoever. Sales rep with common sense! I really liked that everyone I encountered that day had amazing listening skills. This was the 1st and only location I visited and I ended up buying a car that same day. I did not feel the need to go anywhere else. This seemed like a good team to do business with and so I purchased used Toyota Prius v. I did research prior to visiting this location and cars offered through Carfax, another fantastic website. This Escondido location had big selection of cars. I picked 1 out of at least 4 Toyota Prius vehicles on the lot, I got exactly the car I wanted and fantastic experience. Financing option was easy easy and short. Less than 5 minutes. They need your stated income, DL and then after submission, different banks offer different interest rates based on your credit rating. I lowered both my interest and monthly payment by offering larger down payment. However, that's up to you. 20% down definitely gives you better options. At the end I received copy of all documents included Carfax print out. All nicely put together in the folder by a manager. I did drive for about 30 min 2 cars prior to purchase. Highway and streets. I liked optional insurance products such as GAP and LoJack Theft Deterrent. Although I was asked if I want it, it's optional, I was willing to pay extra $795 for each, however now I have vehicle that can be tracked and recovered if stolen by police. I also checked You Tube videos on this, and I love it. The manager Diego gave me Free Oil Check for the future, number for insurance that ended up giving me cheap rate yet fantastic policy the following day. Vehicle I bought was all nice and clean, everything ready and prepared to go! Great people, great experience, highly recommend.

Best Place to buy a used car for sure
"Me and my family purchased four vehicles from Auto City...." - brianwoodward57 Me and my family purchased four vehicles from Auto City. Each time, there is no nonsense, no pressure and no games. They are very helpful when choosing a car and getting financing. There is no price haggling because the prices are extremely fair...and I know how to verify the value of a vehicle. I recently purchased a 2019 Nissan Sentra with all the fixins'. I purchased the car for about $900 less than any other dealership I shopped. Plus, it was in great condition, except for some minor things one would expect a used car to have...but their service department fixed them very quickly and perfectly. My last car I purchased at Auto City was a 2011 Chrysler 200 which had 54000 miles. I am still driving that car in the family and it currently has 218,000 miles. My son bought a Toyota Matrix and drove Uber for 3 years, trading it in with 230,000 miles. Another car bought was a Chevrolet Malibu that was purchased and is driving great with no problems and well over 100,000 miles. All of the cars we purchased had no problem other than an alternator, battery and minor things like that when cars reached over 160,000 miles, and this is to be expected. We never had any major issues with any car, and no problem until many miles later after purchase. My most recent purchase at Auto City took in to consideration that I was self-employed this time. Isaac Duran, the finance manager, did everything in his power to get financing with a lower interest rate, and he did it. All I can say is that if you go anywhere else, you will pay more, put up with weird sales games and miss out on an easy, positive experience in buying a car. And, to boot, they will stand by your car for 6 months, 6,000 miles along side the dealer warranty (they have a huge auto service department to ensure the cars they sell are good). They have always backed us up and made buying a car a positive, easy, confident and a no-risk transaction. Anywhere else I went to check, I always got the "weird-ar" pegging out. Very good, honest people and great cars, with no worries! This is a very positive review, but there is truly nothing I can complain about after buying all of our family cars there for years. Talk to salesperson Mike or Alex...they are both very helpful, friendly and know what they are doing. The sales manager is great and ensures everything goes quick, smooth and I get a good deal.
Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!
