Over the years I've purchased several new cars but this may have been one of the easiest transactions I've experienced. Thanks to my sales rep Lorenzo Edwards we started on a telephone call and I explained what I wanted and we went back-and-forth and we actually made the deal over the phone After visiting the dealership Lorenzo had the Yukon ready for me when I arrived. The paperwork was fairly easy. Thanks to everyone at Simpson GMC.
I had a great vehicle purchasing experience with Seth. He had a great wealth of knowledge about not only the vehicles we looked at, but also the inner workings of the auto market. I thoroughly enjoyed chatting with him, although I’m sorry that he had to spend his birthday evening listening to my stories! My family has purchased many vehicles with this dealership, and we will probably continue to do so simply because of the courtesy we’ve always been shown. I really liked that they do not have any additional markups, at least on the trucks I looked at. Edit - I need to follow up with add-on part of my earlier review. I was very satisfied with my sales experience with Seth. However, after going over my purchase contract later on, I realized that I was charged for 4 add-ons that were listed on the vehicle as "No Charge", and had been pointed out to me by Seth as being included in the purchase price. These items are in the so called Simpson Advantage Package and include the CilaJet, Windshield Protect, Theft Code, and Catalytic Convertor Etch. I know that I signed for them during the documents stage of the process, but I believed I was just being informed of their value. Once I opened the actual contract at home to review, I realized that I had been charged for them. I have since been back to the dealership and I looked at other vehicles and all these items are listed as "no charge" on the small window sticker. I would like to be contacted by the dealer to have this explained and rectified.
I would suggest all dealers to come & take a masters class on sales & Customer service. Just picked up a truck from Andrew Luna, emails communication was very clear, responsive and down to details. I ended up driving 1.5 hours from Santa Clarita to pick up the car & I am glad I did. He got me in & out in what I consider record time at any dealer. I want to also point out the paperwork part, I am not sure what it was called but all paperwork is signed on a large monitor on a desk , Makes it a lot easier for us to review instead of paper & smoothly move forward. All paperwork is giving in a USB I don't need to worry about scan to send it to my accountant. I have picked up cars from many dealer. overall 5 star, I just drove back home & after a long day wanted to leave this review. Owners of this dealership should be proud,
10/10 recommend Simpson Buick GMC Cadillac of Buena Park. Called in to schedule an appointment for a recall on my vehicle. The customer service rep was friendly and efficient. Took my car in and my service advisor Ray was also friendly and answered all my questions. He also informed me of Simpson’s courtesy 2-way uber in the event you need to drop off/pick up your car. Overall, my experience was fast, efficient and friendly. ⭐️⭐️⭐️⭐️⭐️
I've had nothing but exceptional experiences with this dealership's service department. My service advisor, Ray, is absolutely outstanding. Every time I bring my vehicle in, I simply explain what's going on, and he makes sure everything is taken care of from start to finish. He's knowledgeable, honest, responsive, and incredibly easy to work with, which gives me complete confidence every time I need service. I'm always confident that anything my car needs is properly diagnosed and fully resolved before I leave. I never have to worry about whether something was overlooked because I know Ray and the service team genuinely care about doing the job right the first time. The entire staff deserves recognition as well. Everyone is friendly, welcoming, and always willing to help with anything I need. It's clear that customer service is a priority here, and it shows in every interaction. I truly wouldn't trust my vehicle with anyone else. This dealership consistently makes the service experience easy, stress-free, and professional. I highly recommend them to anyone looking for a service team that genuinely cares about their customers and stands behind their work.
