Very professional, courteous and knowledgeable

I brought my truck in to be evaluated with a coolant leak and they replaced the radiator. The next morning I still had coolant leaking and my air conditioner was not working ( it was working fine when I dropped the car off). Also the fan stoped working.

Efrain Guerrero was excellent in servicing the car! Great team at the South Bay location.

Nathan was my salesman and he did a great job explaining everything.

Had no appointment brought my Truck in on a Friday Morning and your service department with Service advisor Efrain Guerrero did a Great Job on taking Care of Me!!

Fast in coming up with deals which is good. But not a very good job in explaining contracts

Was in and out

It was one of the best experiences I’ve had while trying to buy a car, I felt welcome from the second I arrived

Good service

Everyone was friendly. Dealership is clean and welcoming. Geier and Manager Brain were very knowledgeable about purchase i made(2026 Terrain) and the financing. I really liked that they weren't pushy and they were not just trying to make a sell. Excellent customer service.

Reggie is AMAZING, as well as the rest of your entire team. They always take good care of my car.

Jack provided great service and kept me abreast of what was happening during my service

Really helpful

I'm very grateful for my service advisor (Efrain Guerrero) who persisted and got me a loaner during what turned about to be a 2 week period for my car issue to be diagnosed and repaired. I want to highlight the 5 star excellence of Efrain Guerrero in the Service Dept. He is professional, informative, doesn't talk over you, listens very well, provides followup, and is thorough. Thank you Efrain!!

I was helped right away Jose was very tentative to my needs

It was an excellent choice I made, no regrets, I really liked their customer service and for being a first time buyer it was a great deal they offered me on a blink of an eye. sales man Tyler Colbert was really helpful and professional. I would definitely recommend anyone who’s interested in a GMC, Cadillac or Buick.

I’d like to share my appreciation for Sanya at Penske GMC South Bay and the outstanding experience I had purchasing my 2026 GMC Yukon. From start to finish, Sanya was professional, knowledgeable, and genuinely attentive. What truly set her apart was her responsiveness and dedication. She consistently answered my follow-up questions promptly and thoroughly, even taking the time to respond on her days off. That level of commitment and customer care is rare and greatly appreciated. Sanya made the entire buying process smooth, transparent, and stress-free. I never felt rushed or pressured, and she followed through on every detail to ensure I felt confident and comfortable with my purchase. It’s clear she truly cares about her customers and takes pride in providing excellent service. If you’re considering purchasing a vehicle from Penske GMC South Bay, I highly recommend asking for Sanya. She went above and beyond, and I wouldn’t hesitate to work with her again.

Amazing .....The agent was excellent , very knowledgeable courteous , keep up the good work .

it was fine

Best customer service

I always bring my car to Penske because of your associate Efrain Guerrero. I can always count on him to carefully evaluate my car & give great customer service. He is very professional & knowledgeable and I trust him completely. Thank you!!!!

I had one of the best service experiences ever today. A RED SERVICE BRAKES Warning Light came on last night. I took the car in today, a holiday, in the middle of the afternoon. The service department was extremely busy. Reggie Shelton, Assistant Service Manager was knowledgeable, gracious, and extremely personal. He quickly identified the the brake issue and took my car back, even though there were no more service appointments. The inspection revealed that the pad monitor was not working and the brakes didn't need any work. Reggie helped me set up a schedule for Penske to inspect my brakes. He didn't charge me for the service, and even washed my car. Penske will have my business now, and I look forward to working with Reggie and the excellent service team at Penske Buick GMC. South Bay. Thank you so very much!

Everything worked out well. It was my first time working with Efrain and he was very thorough with knowledge of my needs. I will continue to have my car serviced at Penske. Thank you.

Salesman Grear was very good, nice and informative. Great personality.

It was very good and the customer service was great.

We are very pleased with the level of professionalism however we are still have issues with safety

Cathy and the team were amazing. They were very efficient and organized and delivered the perfect vehicle for our family! thank you!

friendly and communicative staff

I have bought many cars, and from my experience, this has been the best so far. I initially planned to buy from another dealer, but based on my experience there, I had to walk out. When I came to this dealership, I was still in a defensive mood. Thanks to Mohammad and his team, I went home satisfied. I felt respected and was not pressured or mistreated.

My experience buying a car was excellent from start to finish. Nathan was amazing to work with he communicated very well throughout the entire process and made everything smooth and easy. He was patient, knowledgeable, and always available to answer my questions. The whole experience was stress-free, and I truly appreciated how simple he made everything. I highly recommend working with Nathan and Mo if you’re looking for a great car-buying experience.

We had a very good and easy experience with all that were involved in the two leases we did on 2/10/26. We had visited several dealerships prior to Penske and none even tried to work with us to get us where we needed to be. The manager and salesperson literally made the whole process stress free.

Service was outstanding, our salesman Tyler Colbert was very helpful and made sure all our question were answered. I would strongly recommend Penske Southbay GMC Cadillac to my friends

It was a good experience

Great

Bob was great. Understood I wanted in and out and provided the pricing I was looking for with ease. I sent out numerous requests from various dealers and Bob understood what type of buyer I was. It felt more like the high end dealerships I have purchased Aston martins, Lamborghinis, Mercedes, BMW, etc. It was a no nonsense experience and that is rare when buying an American car. Most other dealers were playing games and the sales people were inexperienced. Thank you for Bob and your dealership

Nathan was great. So knowledgeable and friendly.

The person, Robert Wright, who took my car ticket was not very informative to me about what was going on with my car and he took a vacation. My car was there way too long and I just don’t wanna deal with his services ever.

I had an outstanding experience at Penske Cadillac, and I want to personally thank Dino, Mark, Reggie, Efren, and the entire staff for going above and beyond. From the moment I walked in, everyone was professional, welcoming, and genuinely committed to making sure I had a great experience. They took the time to answer all my questions, made the process smooth and stress-free, and truly went the extra mile to ensure everything was perfect. Thanks to their help, I ended up purchasing a 2025 GMC Acadia that we absolutely love. Their attention to detail, honesty, and customer service made all the difference. It’s rare to find a team that cares this much about their customers, and Penske Cadillac exceeded my expectations in every way. I highly recommend them to anyone looking for a great vehicle and an even better buying experience. Thank you again to Dino, Mark, Reggie, Efren, and the entire Penske team!

Atanas was very helpful and kind! He had the vehicle ready for us to look at when we arrived and made the buying process easy. We really appreciate the the whole team and will definitely come back to purchase again.
