If you are looking for a new/used vehicle I highly
If you are looking for a new/used vehicle I highly recommend Jason Bardell. His customer service cannot be beat. We made one phone call in the morning and were signing papers for our new 2026 Traverse that evening. He went above and beyond for my husband and I. Thank you Jason and Bocker Auto Group. We love our new SUV! Bob and Jackie Shaffer
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!

As someone who had just immigrated from Korea, I had to
As someone who had just immigrated from Korea, I had to purchase a used car due to budget constraints. While I would have loved to buy a BMW, I ended up purchasing a Hyundai Santa Fe that BMW had taken in as a trade-in. The dealer I worked with, Gennaro, was exceptionally kind and responsible—so much so that he genuinely influenced my perception of BMW as a brand. One of the main reasons I chose this vehicle over cars from general used-car dealers was the trust I had in BMW’s basic inspection and standards. However, the way Gennaro handled everything afterward gave me even greater confidence that I had made the right decision. Having just arrived in the U.S., everything felt unfamiliar and overwhelming at times, but this experience reminded me that there are truly good people here. Honestly, when the time comes for me to change cars in the future, I sincerely hope to return to BMW and purchase a new car from Gennaro. I would even say that owning a BMW through him has become one of my mid- to long-term goals for my life as an immigrant over the next five years.

I went in last week to check out a 2019 Honda Accord
I went in last week to check out a 2019 Honda Accord EX-L, only because it was close to another car I was scheduled to test down the road in Pasadena. May sales rep was Mark and he's awesome. He is extremely helpful and knowledgeable and even better, showed me with minimal research that the other car I was going to see had TWO previous accidents (shame on me for not seeing that) and they met me at the price I needed. So I ended up buying the Accord (very low mileage) at a great price. The best part was how easy Mark made the experience. My wife is on the loan but she didn't even have to be there. I drove the car off the lot about 2 hours after I arrived. They let me keep my old Honda in the lot until we were able to return that afternoon to pick it up. Overall the best car buying experience we've ever had. Thanks Mark and JBA Auto!
