Thorson Buick & GMC

I recently had one of the most frustrating dealership experiences I have ever encountered while trying to purchase a used 2025 GMC Sierra EV from Thorson Pasadena GMC. After seeing the truck listed on their website, I immediately called on a Friday and spoke with Walter. I explained my situation, my interest level, and my trade in details for my 2018 Ford Raptor. Walter had me complete the appraisal forms and gave me an acceptable offer on the trade in and assured me that he would make the truck available for me to buy on Monday. Because I live more than an hour away and had family commitments over the weekend, I could not come in sooner, and he acknowledged and agreed to hold the vehicle by placing it in service status. Monday morning, we confirmed my arrival time by text. Everything seemed squared away. After driving nearly an hour, I was two minutes away when I received a call from Chris informing me that the truck had just been sold. I still went inside the dealership to speak with the sales manager. Instead of any meaningful explanation or accountability, I got a simple shrug and a reminder that they “do not hold cars,” completely ignoring the fact that their team had already agreed to do exactly that. No real apology, no remorse, no ownership, just indifference. Chris and another associate, Jonathan, did offer to try to locate a similar truck at auction and deliver it to my home for inspection, which at the time felt like a decent attempt to make things right. Unfortunately, that promise turned into nothing as well. I never received a follow up call, not a single update, and no apology from anyone at the dealership. I was essentially ghosted after being told they would help correct the situation. I had gone out of my way to prepare my trade in, rearranged my schedule, and drove a long distance based entirely on their word. The lack of communication, broken commitments, and complete disregard for a customer’s time was incredibly disappointing. Thankfully, I found the same model Sierra EV at Culver City Chevy, where I was treated with professionalism and respect from start to finish. I would strongly caution anyone considering working with Thornton Pasadena GMC. My experience showed poor communication, poor internal coordination, and a willingness to make commitments they do not honor.

Ted was great to work with. Very straight forward and honest which I greatly appreciate in this industry. Jose was great as well. Definitely will be back for other purchases.

Recently got a 2023 GMC Canyon AT4 from this dealership. I would recommend working with Aga (salesperson) and Joe (sales manager). It took about a week to get the deal ironed out, but in the end, the deal was fair for both sides and they definitely showed they were willing to work with me to make it happen.

I would not recommend this dealership. They lure you in with discounts on cars that they later won’t honor, they won’t negotiate in good faith at all but instead expect you to make all the concessions. They initially provided me a written quote that I accepted, then backed off the quote in an attempt to get more money out of me.

The best customer service experience I’ve ever had. Staff was top notch! Ted took great care of me from start to driving away! I will be coming back for all my GMC purchases!!!
