Great
Awesome experience. The sales reps here know what it takes to get You on the car you chose. Even before we arrived we knew and they knew the car we were there for. The rep came out with the keys ready for us to test drive. We came back Halley and they were able and willing to get the paper work rolling. We left extremely happy with every aspect of the experience. They even picked up my trade in Which happened to break down on the way to trade it in. They came and picked it up anyway. Awesome work guys. Auto city in Rl Cajon rocks keep up the standard guys
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!

Best Car Buying Experience Ever!
I contacted El Cajon Mitsubishi about a car they had on their website and I can't say enough good things about my car buying experience with these guys from the very beginning. If you are on the market for a vehicle you should give this dealership a try. The Super Team of Terry, Bob, Annie and Matt helped us get the car we wanted without any hassles (oh wait did I said car) let me clarify that; it should be cars (plural) we drove from AZ and ended up buying a car for my wife as well, both cars had low miles and the price was great. This is by far the best car buying process I've ever had in my entire life and I have bought plenty of cars. These guys are straight forward professionals and there is absolutely NO BS when dealing with them. I highly recommend them and if I ever decide to upgrade I'll definitely be taking my business back to them. Thanks again guys and keep up the good work!

I had a great buying experience at BMW of Murrieta.
I had a great buying experience at BMW of Murrieta. Rodrigo and Danny from sales were great. They understood my expectations and exceeded them. I would recommend purchase a vehicle from BMW of murrieta because they treat their clients like family. Also, Ronaldo from Service was great as well. He is my go to for any service on my BMWs. Thank you guys again for an awesome team you have.

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.

My name is Clara ann Swanson.
My husband Paul and I recently purchased a '06 Saturn ION from CarMax in Kearney Mesa. We were greeted with friendly and professional service. The purchase went smoothly and we are happy with our Saturn Ion.
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

Go see Austin Webb - Great young man!
Emailed through Cars.com on a specific Ford Fusion Energi. Austin Webb responded in a few minutes and made arrangements to go see the car. Easy, no pressure, very friendly. We made a deal and I drove home in the Fusion. The dealer is very small - unlike many other dealers I have been to. They are friendly, efficient and no games. Highly recommend Encinitas Ford. I will be back there buying again in the future for sure.
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.

I live in San Diego drove up to KG CUSTOMS to have some work done to my Shelby . These guys are great and very honest . I want to thank JC Barajas and Ruben Pina and the mechanic ,sorry I didn't get his name but thanks to all.
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!

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.
Overall I am very happy with my new Truck.

To my own fault to an otherwise 5-star experience
To my own mishap of making the wrong assumptions to an otherwise 5-star experience. For new car buyers, please read your paperwork carefully and never assume. With all things considered, I would give my experience purchasing my new Corolla at Mossy a 3.5-star. The experience was positive because: 1/ My sales rep Cliff (1) kindly provided me a ride from a nearby car rental to their dealership, (2) was willing to readjust our appointment, (3) offered me a fair price and interest rate, which is greatly appreciated. 2/ The moment I walked in the dealership, I was immediately attended by this lady (sorry I don’t know your name) who was very kind and lovely. It made me feel at ease and well-respected. The process could have been more stress-free and pleasant if Mossy: 1/ Had a comprehensive inventory of cars readily available for test drive, finish the paperwork, and take the car all in one-visit. 2/ If more than a visit is needed, I would appreciate if Mossy can share the warranty & optional add-ons in advance instead of having me made the decision right on the spot. Even though the outcome likely be the same (me purchasing a valid, truly cost-saving security + warranty package plan), the means used to reach that end are worlds apart. Whenever I was forced with a “limited time offer” or “only this time offer,” it’s hard for me to feel confident in deciding because I did not feel prepared. The experience would have been a 4.5 or close to a 5-star if I was not put under such unnecessary stress which can be easily avoided/ minimized if the information is offered (either via phone calls or emails) days in advance. For something that was listed as below: Individual plan: Security system, $720 5Y/55K warranty, $1605 Package plan: Security system + 5Y/55K warranty, $1655 It would have been a much more positive experience if Tom EXPLICITLY clarified that despite the security system and the 5Y/55K warranty were individually listed as $720 and $1600, respectively, when they were bundled together, please DO NOT ASSUME that the security system is now only $50, with the 5Y/55K warranty stays refundable at $1605. I wanted to sign something that I actually agreed to (security system for $50 + 5Y/55K warranty for refundable $1600), not something I thought I agreed to but turned out to be falsely misunderstood (security system for $1030 + 5Y/55K warranty for refundable $625) and later consoled that it is still a pretty good plan. 3/ Avoid using multiple thus confusing abbreviations like TSRP, MSRP, DSRP, SRP. Confusion >>> distrust >>> negative experience >>> negative review, zero referrals, or clients never coming back.

Great experience
I had the car I wanted transferred in and from start to end they kept me informed. The waiting period was a bit of a bummer, but knowing that my car was arriving made it worth the wait. Ryan was super he completed the transaction and put us in good hands. We had a minor defect with the windows but Ryan made sure it was taken care of . Overall we were quite pleased. We're definitely getting a second car with them . Lidia
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.

I am very pleased!
I have purchased my last two used cars from this dealership and I’m happy with how everything went. I was in and out in just a couple of hours both times. They provide a hassle-free, easy experience and get right down to business. Bottom line, I got a great deal on my trade-in, they gave me a lower interest rate than my trusted bank did, and they were not pushy in the least. Another huge plus is that the dealership seemed really scrupulous about safety protocols and keeping things clean among this Covid crisis. They wiped down the keys every time they handed them to me, they wore masks, and the Finance Manager had a glass screen in front of his desk. I felt safe there.
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!

My Work horse.
I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.
