Higher quality customer service they personally have great performance guidance very clear fast and very reliable educated taking care my wife and I Very special
2022 Acura MDX review
I've been driving this SUV for 32 mos. and can say that I love the acceleration and overall handling. However,the suspension is not the best (they saved the best for the Type-S). The gas mileage is just ok but you are driving a great sounding V6 versus a screaming 4-cyl. turbo. I never liked the look of prior generations and was very surprised by the stunning styling of this generation. I'm fine with the infotainment pad, it works great except for the phone charging pad which is junk. I could go either way for a touchscreen but I think that may be more distracting

2026 Acura MDX review
A Spec Advance has all the features I need and is super comfortable. Massaging seats, heated steering wheel, heads up display and just the right amount of tech. This is not the top line model but darn close. Great punch for the price amongst comparables and has the quality and reliabilty from Honda/Acura that you can count on.

2024 Acura MDX review
This SUV is awesome. It is surprising how comfortable and roomy is yet maneuvers so well in tight spaces like parking lots. It has a 3rd row seating which I will not likely ever use but it lays completely flat, so there is no loss of room. The rear area has plenty of room for 4 bags of golf clubs. We drove it to Las Vegas from SoCal last weekend and are really pleased with it.

DCH Tustin Acura review
Acura has a policy to replace or repair malfuntioning seatbelts for the life of the car. I took my 2000 TL in because the passenger side seatbelt retractor was locking and not releasing. The driverside seatbelt wasn't retracting well. This is a 17 year old car and Freddie didn't hesitate to take care of the problems by replacing both retractors...they even washed the car, all for free. ***** ?
2023 Acura MDX review
It is a very nice vehicle… a few exceptions… no heated steering wheel, no remote start no foot controlled rear lift gate and a few other amenities that comes with many other comparable vehicles. The trim levels do not make a lot of sense like aspec is considerably more expensive but only a few amenities and the advanced is almost 20k more for a few options that are stock with Lexus and other high end suv…

Phat's Auto Group review
I spoke to Phat on the phone. Everything he told me was true. The person who helped me when I came in was courteous and knowledgeable about the truck. He gave me the key and let me drive it. I didn’t realize how much larger the Tundra is over a Tacoma. I didn’t buy because I like a smaller truck. My helper understood and did not try to pressure me. I would recommend Phat’s to anyone looking for a used car or truck.

2023 Acura MDX review
Like other reviews I love this car! Comfortable, stylish, it’s inherently a Honda so likely reliable. Gas mileage not great but better than MDX of the past which weren’t nearly as fun to drive! Highly recommend this Acura. Haven’t owned one since I had a 2008 TL but I have the same happy feeling whenever I drive it, now in a very different life stage!

The process was easy and smooth. The time it took from start to finish lasted almost 5 hours and that?s with no trade in or financing. That surprised me.
2026 Acura MDX review
The Aspec Advance MDX punches way above its class. For the price point, you get all the bells and whistles. Compared to other higher end SUVs, you don’t have to add anything. It has massaging front seats that are heated and ventilated. It has a 19 speaker deluxe sound system. It also has a heated steering wheel and many other features. It drives like a dream smooth and quiet. Great road trip vehicle!

Lexus of Cerritos review
I have been coming to the same dealership since 2018 and have zero complaints. I don't feel like I am being "sold" too and my service rep is upmost and honest about what is required for general maintenance. I choose whether to have it serviced there or pass. I will continue to tell others to go there and hope they experience the same quality of service as I do.
2020 Acura TLX review
I absolutely love the 2020 Acura TLX. I traded in my 2013 Honda Crosstour for it. The Crosstour had a lot (3.5 6cyl )EXL. It took a little time to get used to the TLX 4cyl, FWD set up. The Dual Clutch transmission is a little quirky. Overall the car is fun and comfortable to drive. I honestlt think Blind Spot should be a base feature is all cars. CPO

We’ve owned Acura’s since 1991. Have had sedans and SUV’s. Both MDX and RDX. This is the best one yet. The technology is unbelievable. The ride is superb. The comfort and roominess are second to none. The safety features are remarkable. Can’t say enough about this vehicle.

2023 Acura MDX review
We love our 2023 Acura MDX -- handling, ride (in all modes), acceleration (definitely enough when you need it to enter the highway, etc.), interior, dependability, technology and size. This car is the perfect size for us with 3 dogs. We make lots of trips to the park and of course, to stores regularly too. We do lots of DIY projects too so we need to haul materials. The MDX offers plenty of space to do it. The gas mileage is great (25 mpg+ in the city for us) -> much better than the under 10 mpg we had been getting with our 2018 truck. Very pleased with the versatility of the MDX.

2015 Acura MDX review
I recently had the pleasure of test-driving a 2015 Acura MDX from the CarLoft dealership, and I must say, I was thoroughly impressed with this premium SUV. The Acura MDX has long been known for its blend of luxury, performance, and reliability, and the 2015 model certainly lives up to that reputation. In summary, the 2015 Acura MDX from the CarLoft dealership is a fantastic choice for those seeking a luxury SUV with a proven reliability and performance track record. While it may lack some of the latest tech found in newer models, it makes up for its timeless design, comfortable interior, and a driving experience that combines power and refinement. If you're in the market for a pre-owned luxury SUV, the 2015 Acura MDX is worth considering.

This is one of the largest CarMax that I've been to and they have quite a selection of cars. The salesperson was not pushy and were very friendly.

CarMax Serramonte review
I had no choice, my car of 20 years, which I bought brand new in 1999 was done. With so many websites ( I looked at several), I was not sure where to go. Then someone mentioned Car Max to me. I looked on line and saw a few cars I was interested in. The next weekend I drove to Colma to checked out and test drive a couple of cars. I decided to ask about Hybrids...you had 2. I test drove one of them and could not resist. I bought it. I was very impressed with the buying process. It was quick, easy and believe it or not relaxing since the sales person completed the paper work for me. Yes, I had to sign several sheets but that was a given. Something I was dreading for the past two years, was so surprisingly easy I couldn't believe it!!!
2016 Acura ILX review
Equip with a beautiful duel clutch transmission, this car feels amazing to drive, up until about 40, where the early gears start to lag, but as suggested sport mode or down shifting solves this. Coming from a Honda civic 2017, I can say this car although slightly dated in the inside, feels loads more powerful and comfortable. With seats that hug your body, giving you one of the most comfortable seats out of any car period. The ride itself is great too, although a tad stiff, which in it's self gives it good handling and corning in return. The only big con is the interior is a little dated compared to newer cars, so not a whole lot of smart phone integration besides aux, usb, or Bluetooth, although this means less issues with electrical issues like my old Honda had. Overall I couldn't recommend this car enough, as when buying used it is far cheaper and better than comparative civic models like the ext or si.
