STG Auto Group of Montclair

Google Reviews

I had a great experience at STG Auto Group. One of the first things I noticed was how clean and well-maintained all the cars were, every vehicle looked sharp and ready to drive, which isn’t always the case at other dealerships.

Randy helped us out, and he was awesome to work with. He’s knowledgeable, easy to talk to, and really listened to what we wanted without pushing anything extra. It felt like he genuinely cared about helping us find the right fit.

The whole process was smooth and straightforward, and I left feeling really good about my purchase.

Buyer Beware: My Disappointing Experience with STG Dealership

This review is based on my experience with STG’s deceitful, dishonest, and unreliable business practices, along with their rude and unprofessional customer service — from the front desk receptionist to the service department staff (Marina, in particular).

This was my second time purchasing a vehicle from STG, and unfortunately, history repeated itself. The first time, they lied about services they promised to uphold. Because I didn’t ensure it was written in the contract, they refused to honor their word. I let it go at the time since I was able to resolve the issue elsewhere without much hassle.

Fast-forward to this past month — I returned to STG because of their wide vehicle selection and seemingly reasonable prices. I’m now kicking myself for not choosing a reputable dealership.

The Sales Experience

I dealt with Carlos, Ramy, Anthony (sales manager), and others at their Montclair location. The car I purchased wasn’t actually there; instead, I got a message from Anthony at their Bellflower location saying the car was being transported. That was around 9 a.m., so I drove down to Montclair — only to end up waiting over four hours for it to arrive.

During that time, Ramy had me sign all the paperwork while the car was still in transit. He kept assuring me, “You’re going to love the car — it’s a great car.” Foolishly, I trusted his word and didn’t inspect the vehicle before signing.

When the car finally arrived, I immediately noticed numerous scratches, deep dings, and a rough interior that clearly needed a professional detailing. I pointed these issues out, and they assured me everything would be fixed. We shook hands, and I believed them.

Broken Promises

I made an appointment with their service department, where I was attended by Marina. She immediately told me they wouldn’t repair anything because it wasn’t listed on their “due bill.” I explained that Ramy had promised the fixes verbally, but she refused to honor it.

I left the vehicle with them for nearly a week, and when I picked it up, it was in worse condition than when I dropped it off. None of the promised work had been done.

When I tried to reach out for resolution, I was constantly given the runaround. Anthony (sales manager) even hung up on me, and neither Carlos nor Ramy would return my calls.

Deceptive Add-Ons and Overcharges

On top of everything else, they tried to charge me $900 for window tinting and another $900 for door bumper guards — both outrageously overpriced. After some haggling, I got the price lowered, but the tint job had bubbles, and the car still had visible scratches.

Final Thoughts

This dealership will say anything to make a sale and get you out the door, but once they have your money, you’re on your own.

If you’re considering buying from STG, learn from my mistake:

Get everything in writing. Make sure all promises are clearly listed on your due bill.

Don’t pay for overpriced extras like tint, door guards, or GPS add-ons.

And most importantly, take your business to a reputable dealership that values honesty and customer satisfaction.

Buyer beware — once you drive off their lot, STG stops caring.

I had an outstanding experience at this dealership from start to finish. The entire team was welcoming, professional, and genuinely focused on making sure I drove away happy. The showroom was clean, organized, and had a great selection of vehicles to choose from.

A huge thank-you to Fernando, the sales manager, who truly went above and beyond. Fernando was knowledgeable, transparent, and never pushy. He took the time to listen to what I wanted, answered all of my questions thoroughly, and made the entire process smooth and stress-free. It’s rare to find someone who combines professionalism with such a personable and trustworthy approach.

Thanks to Fernando and the team, I felt confident and excited about my purchase. I highly recommend this dealership to anyone looking for an excellent car-buying experience—you’ll be in great hands!
