Our Reviews

Tony Rezakhani in sales was amazing and truly went the extra mile to help me find exactly what I was looking for. I’ve never seen another dealership come close to that level of customer service. I can’t recommend your dealership enough.

Straight forward car buying experience and financing helped explain a few options that helped in getting a better rate. Overall happy with purchase process.

Jose, terrific! Great knowledge and a wonderful personality. He answered all my questions!

I called on a Saturdsy and there was not an appointment until Tuesday. But Jose told me if I could bring it in that day, we would get me in the queue as soon as possible. He bent over backward because he knew I needed my truck to go on a road trip that Wednesday. He communicated status throughout the process and my car was done on Monday afternoon! Great service!

Very good service.

on time and great experience

Jackson was great! Always greets with a smile and is very responsive

Great service.

My experience was great. Jackson was extremely customer service oriented and did a good job communicating my service timeline. Overall, the experience was enjoyable and would return for future services.

First time in all the years I been there for service that I got an excellent service that use his time to explaining things Thank you

Very easy to work with, service was thorough. I love that they sent a follow up email with a video of my technician and my car.

I love going here for service. It's quick, easy, great place to hang out if you're waiting. All of the service advisors are so nice & patient. My advisor Jackson Smith does a great job going thru what is needed and helps prioritize.

Great team, quick service, and overall good people that I found myself talking to.

Jose is always nice, respectful & most important on top of things, follows up and keeps me informed. Great Service!

Mason from Allen GMC/Cadillac service department was very professional, answered all my questions and was able to service my GMC Sierra truck in a timely manner that fit my schedule. I am the original owner of my 2001 GMC Sierra 1500HD. I've taken great care of my truck over the years and in turn the truck has provided great service to me. When the time comes I will look forward to purchasing another GMC vehicle.

Quick and easy

Jackson is very professional and responsive. Always the best service rep.

Steve great and worked with me respecting the issue with my truck’s radio! Got it back to me in good order. Always get a loaner vehicle and Norma gets me out in a flash.

You guys are awesome!

Jackson is great! Great service and very pleasant to work with. My wife and I do not like your 3% extra charge to use a credit card to pay you. This should be part of your cost of doing business not a cost of ours to do business with you.

Jackson was excellent. He kept me updated on the back ordered part and then got the vehicle fixed in one day.

Friendly& competent!!!

Great job, thank you!

Excellent service team, and technicians always get the job done right the first time !

Such an easy process and was made extra special with the help from my sales agent AB! Such a great guy and really took the time to help me into the best truck/payment that suited my needs.

The service was great and the truck wash after the oil change was really impressive. The dealership is charging a 3% Credit Card fee which is childish. Just charge everyone more instead of alienating most people who pay with credit cards. Silly business practice and a deterrent to me returning for next service. Will use Valvoline next time.

great

Great experience with transparent pricing and quick service.

Great service, great people. I do have a problem with the additional charge for using my credit card. I wish someone would have informed me. I could have paid in cash, check or debit card.

Great

Uriel was incredible, nice to have a salesman that knows his product.

Needed new tires & a loaner. Quick easy & simple!! All done in under 24 hours! Thank you Jackson for getting me ready for more rain!! :)

staff was great, internet pricing was good and check out was quick. thx

All went smoothly

Jose Morales ,my service advisor, was extremely knowledgeable , friendly ,and professional. He kept informed at all stages of my February 4-6,2026 GMC Acadia repair . He even asked the mechanics to work overtime to finish my car repairs before the weekend. I highly recommend him as an excellent GMC service advisor!!!

Steve is always friendly and helpful, Easy to get my truck serviced.

Easy check-in easy service

Job was completed as promised

Jose is very professional

Very detailed and excellent work. Jackson is always very professional and helpful.

Charging me an extra 3% because I used my credit card was a cheese ball act by a GMC dealership!! Also I believe what they did is illegal in California

Laguna Niguel GMC was an excellent place to purchase my truck. Alan was awesome and the finance guy (forget his name) was also great. I think the entire purchase took only an hour. Working with Alan, and Don via email and text was a really efficient way to make the purchase easier. One small issue with the truck wiring under the dashboard where LoJack was installed, but Alan is working on getting that fixed for me.

Jackson Smith always makes sure our vehicles are well maintained. Jackson provides excellent customer service. Thanks Jackson

The service advisor did a great job.

I had a great experience and this will now be my go-to dealership for service!

Steve Ruzic was awesome, you have a great employee

I appreciate the level of professionalism and customer service. Thank you.

Jose was professional and got everything done quickly for me. It was a great experience.

Always a professional team !!!!

the best in the west, Steve Pacheco and Tim are the best.

The Allen Cadillac GMC Service Department, and Steve Pacheco specifically, continued providing excellent work and more exceptional customer service as usual. Steve always goes above and beyond to make sure I am well taken care of and that my vehicle gets the quality care I expect. My vehicle was repaired completely and on schedule.

Jackson Smith is a great representative of the dealership. Very personable and good communication on progress of repair.

friendly and appreciated the texting option

Friendly and good fast job !

tony the sales rep went above and beyond to make my experience smooth

Incredible purchase experience. A++ service from the entire staff: AB, Don, John, Tiffany and the finance guy. No hidden charges or fees, everything was straight forward and above board. Came in at 7:00pm and we were out by 9:00pm...and were treated like our business mattered. We had more personal contact with Tiffany, she was great!! She was so knowledgeable about the process, the vehicle, and made us feel welcomed. We will be back!! Best car buying experience ever. Thank you all!!

Amazing experience

Stephan was great. Very friendly and knowledgeable.

Like other GMC dealers in the area, "we can't replicate the issue," especially on new (warranty covered) vehciles, yet when I get in the vehicle, I can replicate the issue. Mason and his service team are mediocre. A squeaking seat, "can't replicate the issue." I brought it in a second time, and I had to replicate it in front of them. They then charged me for an alignment on a brand new vehicle and didn't tighten it all the way; my vehicle was out of alignment again within 24 hours. They refused to pay for Uber to get there. I spent a total of $60 for Ubers back and forth for their issues. I asked for a loaner vehicle both times, and they refused, saying I needed to book 5 days ahead of time. Yet, they were giving loaner vehicles to other customers who did NOT book 5 days in advance, which is wrong! I really wish the Allen family still owned this dealership, as we never had issues when they ran the place.

Servicing vehicle was simple and quick. Highly organized and effective staff.

My experience was very good communicating through text and email in regards to making a deal. Tony Rezakhani was professional, thoughtful and kind. Becasaue of my work schedule, the text and email process was a benefit and reduced my overall time spent at the dealership when finalizing with the Finance dept.

It was a long day but a pleasant, low key, experience. I had a limit as to how much I could spend and the salesperson and the finance director worked hard to keep my purchase within my limits. I am very pleased with my new vehicle.

Jose morales did an excellent job as my service advisor . The service team got me in and back out in a timely manner. Great work fellas
