Mark Christopher Chevrolet Buick GMC Cadillac review
Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

Simpson Buick GMC of Buena Park review
Great experience. Simple and easy. Great staff. Definitely would recommend.
2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

2026 GMC Sierra 1500 review
This is my first GMC and I absolutely love my Sierra 1500 Elevation. The 5.3L v8 is more than enough to pull my camper, I love the stylish interior and it is comfortable to drive. I also felt with the financing and discount specials this was a great deal.

Simpson Buick GMC of Buena Park review
Great service friendly and helpful had my Yukon worked on warranty service Ceasar Rivas was helpful and took the time to call me on every step.
2026 GMC Sierra 1500 review
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

CarMax Clackamas review
This 5 stars in for one employee in particular. Tim Gardner in the service dept. My little story... I had recently purchased my vehicle on April 1 & had to return it on April 4th due to the speakers, window and a little idle. It was now 4/16/2018 and my car was still not finished because the speakers were missing a part that need to come from Korea, they told me my car would be finished no later than Monday and that was a promise...So long story short everyone I spoke with said they would call me back and help me figure this out and no one did, they called with the same info about waiting for a part but no new news. Thankfully I called in 4/17/18 to check on my vehicle on when the part will be in and Tim (which was my first time speaking with i'm through these couple of weeks.) and he said the part was scheduled to arrive on 4/24/18 I was furious. Here I am driving loaner cars and not even able to enjoy my new car for a whole month. He listened to me and quickly went into action and said I am going to help you, we are going to fix this. Literally in 2 hours he called back said that they can get my car to a certain place and they can do it if I agree and also offered me a couple of other things and said I will get your car to you by today or tomorrow after he explained this to a manager. All in two hours! and I couldn't get a straight answer for two weeks! Tim called me when it left car max and when it came back and tested the stereo for me himself! He completely turned my whole experience back to a positive one again and now I am truly happy he went above and beyond and keep his word! He was very kind and put actions to his words! He is definitely the highlight of my week! now I can drive my new car thanks to TIM Gardner.! Thank you TIM! You don't know how happy we are!

CarMax Clackamas review
I have never bought a car so easy as I did here. The process was quick and painless just the way I like it. The finance part for the car took like a 10 minute process. The no haggle price is the price and there's no back office person dictating the sales rep to get more money more money on the sale. It's all done at the desk you sit at drone start to finish, just you and the sales rep. I rolled out in my new car in a half hour total.. Loved it(and car is awesome too)
