Always perfect--the cars come back looking like they rolled off the showroom floor. That deep, mirror-finish shine you can see yourself in. They've got a clean, professional setup on Placentia Avenue near 19th Street--appointment-based, call ahead to set up initial s. Easy, no fuss. I text Ehren--he's quick to reply, we set something up, and he sends his crew. They're solid. They cover surrounding areas, even 15 miles out like me. No problem--they show up, do the work. Seats wiped, carpets vacuumed, windows clear, wheels shiny, trim polished. Everything flawless without me saying a word. And those monthly maintenance packages? Great value--keeps everything looking sharp without breaking the bank. Friendly, on time, they care. Call Ehren at Supreme Motors--your cars will look great.

I've never walked into a dealership, asked for the car I had my heart set on, and driven away with everything I hoped for--including terms I never thought would be possible for me. As a single 30-year-old woman buying a car without a co-signer, that meant so much. The team guided me through every step and made the whole experience feel easy. They also gave me a great offer for my beloved Honda Civic, even though it wasn't running and had over 200,000 miles on it. Saying goodbye to that car was emotional, and I appreciated how smoothly they handled that part of the process. A special thank-you to Brian, my sales consultant. He was polite, professional, easy to talk to, and truly the best! He made my day. I'll never forget the day I drove home in my new car or how well everyone at CarMax Duarte treated me. Thank you, Brian and the entire team!

I cannot say enough good things about Sierra Honda in Monrovia and their service department! After…read moretaking my Honda to two other dealerships without anyone being able to figure out the electrical issue, Sierra Honda was the third dealership I tried -- and they finally solved the problem. I had recently had the power cable recall repair performed at another Honda dealership. Unfortunately, during that repair, the power cable was not properly secured. As the car moved and was driven, the cable was able to shift slightly within the connection, causing an intermittent electrical problem that was incredibly difficult to diagnose. This caused multiple times where the cable connection came loose causing the battery to drain, and the car essentially "dying" every few days. The team at Sierra Honda, and service advisor Andreh, took the time to actually investigate the problem instead of simply replacing parts or sending me on my way. They discovered that the power cable was moving within the connection, identified it as the source of the problem, and properly secured it so that it can no longer move or lose connection. After two other dealerships (one being the dealership where the recall repair was done) were unable to find the cause, I was incredibly impressed that Sierra Honda was able to track down such an unusual and frustrating issue. Their thoroughness, persistence, and attention to detail made all the difference. I am extremely grateful to Andreh and the Sierra Honda service team and would highly recommend them, especially if you have a difficult problem that requires real diagnostic work. They earned my trust and will absolutely be my first choice for Honda service going forward. Five stars!

I'm updating my review to reflect what's happened since my last post…read more My truck has been at the dealership's service department since June 25. I finally picked it up on Friday, July 10, hoping everything had been resolved. Unfortunately, on Sunday, July 12, after only a short time of having the truck back, the check engine light came on again. Before picking up the truck, I specifically asked that all diagnostic trouble codes be addressed--not just one issue. My understanding was that there were multiple fault codes, including the turbo gasket, the auxiliary coolant heater pump, and other related issues. Unfortunately, it appears only one repair was completed, and now the check engine light has returned. I reached out to the dealership again but have not yet heard back from Edwin. I do want to recognize Danny, the service advisor, for taking the time to contact me. Even though he was off on Monday, he reached out to let me know he would be back on Tuesday and would do his best to arrange a loaner vehicle. I truly appreciate his communication and willingness to help. The most difficult part of this experience is that I purchased this truck nearly a month ago specifically to tow my food trailer for my business. Instead of being able to work, the truck has spent much of that time in the repair shop. As a small business owner, every day without my tow vehicle means lost income, while I'm still making payments on a truck I haven't been able to rely on. I understand that repairs can sometimes be complex, but I simply hope the dealership will thoroughly diagnose and repair all of the underlying issues this time instead of addressing only one fault at a time. I purchased this truck because I needed a dependable vehicle for work, and I just want it to be safe, reliable, and operating the way it should. I sincerely hope my next update is a positive one.

It smells fresh, leathery, and overpriced. I love going outside, walking the lot, and seeing the BMW's lined up... hungry for a new owner like dogs waiting at the animal shelter. I love waking around the showroom, going into the elevator to see if there are any BMW's upstairs as employees watch me step inside and giggle to themselves. You need a passkey... this was the metaphor for my visit: Entering the elevator, having the doors close, and going nowhere. I love asking two employees in the office by the elevator if there are BMW's upstairs and being told "I can't believe you made it all the way back here without talking to a salesperson. Go to the front counter." Yes, I obviously made it to the elevator, I agree with you entirely, and I guess customer service isn't in your wheelhouse of skills. I love walking my happy butt back to the front counter, which seems like Groundhog Day. Have I been here before? Yes. Is there anyone here to direct me? No. I love waiting. What I did love is driving to a different dealer that actually valued my time, who put me into a 5 series, and made the entire experience enjoyable. That was not BMW of Monrovia.

Exceptional, Stress-Free Experience with Omar Cid at Longo Toyota!…read moreWhen I decided to buy a new Toyota Camry, I started with a Google search to find the best Toyota dealership in Southern California. That led me to several Reddit threads where local drivers almost universally agreed that Longo Toyota was the place to go--citing their massive inventory, fair pricing, and complete lack of pressure tactics. After buying my car here, I can confirm that every word was true. While Longo's incredible selection is a huge plus, the outstanding customer service seems to be a standard practice that all staff genuinely adhere to. Working with Omar Cid was easily the smoothest, most transparent car-buying process I have ever experienced. Too often at other dealerships, you waste hours talking to a salesperson only to face aggressive upsells or find out the finance department flipped the numbers around on you. None of that happened here. Omar was fantastic from start to finish. We spent about 35 to 40 minutes going over Longo's inventory to find the exact Camry I wanted, followed by a quick 30 minutes to run my credit and get my loan approved. When it was time to finalize the paperwork, I spent only 5 to 10 minutes with the finance manager just verifying the loan terms and total price. The finance officer did present the optional add-on services Toyota offers--which Omar had already explained thoroughly beforehand--but there was zero pressure to buy anything extra. If you're shopping for a vehicle, ask for Omar Cid! Between his honesty, expertise, and the top-tier customer service culture across the entire Longo Toyota team, you won't find a better dealership experience.
