Everyone was so helpful! Our salesman Marko was not pressuring at all, and helped us get into the jeep we wanted at a great price with numbers we were comfortable with.

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 xxxxe. 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.

Lies from point A to point B. They are dishonest, thousands in hidden fees that they try to hide or dismiss. You need to read everything twice over in order to not get taken advantage of

I was warned not to come here beforehand, however decided to since I already had an appointment. We show up and the car is already sold. Was communicating back and forth for 3 days and was told we can’t look at it due to it being maintenance, and detailed for the showroom floor. They make us an appointment to come test drive the car so we drive over an hour to come look at this car just for them to sell it before hand with no communication, but also as we arrive they simply did not care at all that we had an appointment and made our day out to come look at the car. Honestly one of if not the absolute worst dealership and business overall I have ever stepped foot into. Unprofessional, careless and is simply a spot I do not recommend at all to anyone under any circumstances. I even tried leaving zero starts and couldn’t so the one star you see isn’t even earned. Don’t waste your time and energy with STG Auto Group of Montclair.

I went there with my Girlfriend to buy a used Fiat EV. Everything was fine for the most part, but the car was missing a charger. The salesman, Jerry, said he'd order a charger for her and that it'd be there next week, and that he would call when it came in. Seemed simple enough. But he never called, and instead dodged all her calls. Then when she finally insisted in talking to a manager, he said they would never do such a thing. On top of that, a headlight and tail light went out barely a month after she got it home, and had driven it maybe five times. She mentioned that, and the supervisor's response was basically, oh well, not our problem. That may be technically true, but if that's how you do business, you are not someone who people should do business with. Buyer beware indeed. These people embody the worst stereotypes of the used car salesmen.

George was incredibly helpful and made everything easy. I’m very happy with my RAV4 deal.
