    If you're looking into a dealership that is very pushy and does not respect your communication, then this is definitely a place for you. I was in the market to look for a new vehicle & I came across this dealership online. They did have a car that I was interested in, so I set up an appointment. On my way to my appointment, my car broke down from the freeway. Also, I was coming from close to 50 miles away. I informed the dealership about my situation and I had 2 different salesmen messaging me: Noah & Cesar. My car actually had broke down on the side of the freeway where steam was coming out of my car. I understand that Noah desperately wants to me a sale but he would not respect or understand my situation. He only wants to make sure he put money in his pocket. That being said, it's completely up to you if you want to work with them. I haven't even step foot into that dealership & I definitely know I will never do so after this experience.

    1 Star - Stay away from STG Auto Group Bought an Acura RDX here on 3/13/26 and it was hands down the worst car-buying experience I've ever had. They lied about add-ons being mandatory, claiming we needed them to get a lower interest rate. That's not true. I even found paperwork during signing that clearly said the add-ons were optional. When I questioned it, the salesperson literally admitted he doesn't like working there because of how they do business. They also told me dealers can't mark up interest rates in California anymore, which is false. Later, someone from their team accidentally confirmed the bank approved me at a LOWER rate than what I was given. We put $5,000 down ($2,700 cash), and they refused to give a receipt for the cash. The car had a brake issue the SAME DAY we drove it home (braking on its own + warning light). It's now been in their shop for almost 3 weeks with: no updates conflicting stories constant runaround I was hung up on by their finance manager and even dealt with someone who gave me info and later turned out they have me a name of someone that did not even work there. This place has zero integrity. Just pressure tactics, lies, and terrible service after the sale. Save yourself the headache--go somewhere else. These guys are scammers: Sales: Georgio (should be how you spell it) Sales Manager: Anthony (bald with tattoos on his neck) Financial Manager: Chris A. (Very childish when speaking to you, over talks you and hangs up on you mid conversation) Fake guy: Tony Suarez

    I had my Porsche Boxster S for sale on auto trader for 52k. Jackson who works in the office offered me 48k and we agreed on 49,750. Lie number 1. Because we agreed on that price I took my car to sell it to them driving 30 minutes each way to get there. They kept me there 2 hours and came back to offer me 47,500. So right off the bat I was LIED to again. Then they offered me 48k and I left. I hate liars. So two hours later I get a call from the manager Klaus, saying the reason they changed the offer was because the transmission had a leak. Funny there's NEVER been a puddle under my car. Then they said the two back tires were different, big deal, they're expensive speed rated tires, a chip on the windshield (another LIE), and "many costly repairs" All total garbage to get the offer low. Jackson wouldn't even come out to talk to me. I was told that the repairs will cost too much to do so they're just going to sell it AS IS. What a crock of shite. This is classic bait and switch. I brought my car back the next day and sold it to them because I didn't want a hefty repair on the transmission which is very suspect. They low ball and lie. NO ONE came out to talk to me, not even Klaus. I'd call that UNPROFESSIONAL... BAD customer relations. I brought an important document of MINE for them to COPY not KEEP, instead Sammy kept it. I need that back by the way. Will I get it? Probably NOT. Fits in with the rest of my experience here. I would say, BUYER BEWARE. I read other reviews before going and they're very bad, (good thing I wasn't buying anything). I can see why. The best customer service there was their free soda. They have nice cars and a LOT of vultures, sales people, on the lot. When I got home I had a text asking me to remove my bad reviews. So I changed them with brevity in mind. I am waiting for the check to clear the bank. I don't trust LIARS. I would NEVER recommend this store to anyone because I was lied to. Look at the other reviews to see how they treat buyers and decide for yourself. I feel sorry for the person who buys the Porsche because they said they're not going to fix anything they had issues with. AS IS BUYER BEWARE. Shame on you STG for your shady business practices. I would NEVER buy a car from you. This is based on my experience and their bad reviews. I've owned a lot of cars in my long life and STG ranks up in my top 3 WORST auto dealers. My suggestions: better customer service and less time on your computer, dress professionally, don't walk around VAPING, stay with your customer during the transaction and don't lie to customers. I'll never return. Now they're selling my car as is with all the issues. BEWARE OF THESE CROOKS. IT DOESN'T HAVE A SECOND KEY because I lost it and look at the damage on the bumper and wheel they didn't fix. Mismatched tires still there? Ya.

    Do not bother trying to sell here, they will waste your time. Had my wife come in at 11:30 and told her it would take a hour, ended up being much longer. When she got there they made her wait for their lunch break to end, and then had her run to different parts of the building to get help and still had to wait another 30+ minutes on top of that. She took time off of work to come in just to lowball us on very minor cosmetic that would be expected with a car at 98k miles when we had said the major issue over the phone which was a small chip in the windshield and still had a agreed upon price before agreeing to come out to avoid this exact situation. She asked for the inspection report and told her they sent it to me and sent her on her way, all I received was an updated offer with the new lower price. Unprofessional and rude to my 9month pregnant wife. (UPDATE: so after blowing my phone up trying to get a deal done they finally offer a additional $200 for disrespecting my wife/wasting her time and so we agree upon the price and they ask for my wife's number to call to confirm. They call her and they sit there on the phone with her ranting getting upset with her for 5-10minutes just to say they won't go over 11k again. Thanks for wasting our time even further)

    Driving from north Hollywood to get the car that I wanted I would say was worth it for me…read moreespecially other dealerships that I couldn't go to that literally wanted me to sell my soul. I love my car but just know that used cars prices are higher in $$$ due to the inflation. Pay attention to the total price of what you are paying than you payments. Your literally buying a old car with new car prices & more. No lie I needed the car badly for work so this info couldn't stop me The process was so long but the people that work with me there were so great. The only thing I would warn about is to make sure you do a through inspection with the car (drive the heck out of the drive test to make sure the light engine doesn't go off) and make sure you get it done at the dealership no matter how long it takes !!! Do not leave the lot without getting everything taken care of. Trust me . I had a couple issues with my purchase and dealing with Bridgecrest was a horrible experience from my monthly payment to my warranty with the car . Don't have high hopes for them especially during these uncertain times (Covid). My only advice to be on top of your account with them and record any interaction with them as the reps share inconsistency in information. The warranty process is even worse,I gave up . Luckily now , my car doesn't have issues And I can enjoy it Hopefully this help Happy car hunting

    Don't sell cars that need repairs within 30 days of purchase or 5 months…read more I purchased a vehicle from DriveTime in April 2024. Within 30 days, the vehicle developed mechanical problems. Rather than resolving these issues at the dealership level, I was directed to use the SilverRock warranty. Despite continued repairs, the vehicle required a complete engine replacement in October 2024. Now in 2025, the vehicle is once again displaying a check engine light, and I am currently addressing possible transmission issues. This has been a long-term reliability concern that has required repeated service visits and significant time and effort. My review is shared for transparency so that other consumers can make an informed decision. I recommend that buyers carefully review vehicle history, inspection reports, and warranty coverage before proceeding with a purchase.

    EXCELLENT Never…read moreexpected it... Friendly, courteous, and very professional. I made a phone call in the morning and spoke to the general manager, Adrian. He took his time to prescreen, finding out what I wanted, not what was convenient for him. I gave him specifics, and he said his sales rep would call. Adrian Jr. called, and we finalized everything over the phone. He listened to everything I had to say. They worked their magic; after hearing my questions, he answered them all without negativity or saying "can't," which is huge when making a big purchase. Upon arriving at the dealership, Adrian Jr. immediately greeted me and showed me my new truck, which was ready to go. Adrian, the general manager, came out to thank me and greet me as well. I received a positive vibe and a smile the entire time. Once we sat down, I was expecting a change before putting pen to paper. BUT NOT WITH THEM!! Everything was as we had agreed upon! They never attempted an upsell. Yuri, in finance, was absolutely awesome. She knew every detail and verified the numbers. She made sure everything matched and corrected any mismatches without hesitation. She never forced upgrades or upcharges. She informed us of options, explained the pros and cons, and our decisions were made without pressure. The experience was the best, from phone etiquette to customer service - top-notch! We were blessed to get our new truck from Mountain View, and we will recommend Adrian Jr. and Yuri to anyone looking for a vehicle. We've definitely made a customer for life; my son is already purchasing his first vehicle from Mountain View. Thank you, Adrian, Adrian Jr., and Yuri; you made us feel important.

    1 estrella - Experiencia totalmente negativa…read more NO recomiendo este dealer bajo ninguna circunstancia. Desde el inicio hubo mentiras, cambios constantes de precio y falta total de ética. Los vendedores son poco profesionales, mal informados y usan tácticas para confundir y distraer al cliente. Tengan muchísimo cuidado al firmar el contrato, ya que lo que prometen verbalmente no coincide con lo que aparece en los números finales. Lamentablemente, por la urgencia, mi esposo terminó comprando el vehículo y fue uno de los peores negocios que hemos hecho. Revisen cada cifra, cada línea y cada cargo, porque no son transparentes ni honestos. Nuestra experiencia fue engaño total y decepción absoluta.
