The dealership continues to send me emails alleging that

The dealership continues to send me emails alleging that they tried contacting me NUMEROUS times at my valid phone number, but were unsuccessful. The emails then go on to say, that NUMEROUS messages were left. NO calls were EVER made to my phone number. NO messages were EVER left. Although the numerous emails state "I", and "We" tried calling and left messages, NOT ONE email EVER identifies WHO was calling, or WHO the "We" was! A reply email was sent addressing these issues, only to receive ANOTHER annoying, unidentified reply alleging the same issues. We, I tried calling, left messages...etc. VERY UNPROFESSIONAL!

I came into Buick GMC of Mahwah with a pre-approval from

I came into Buick GMC of Mahwah with a pre-approval from Capital One. During the financing process, I was shown two numbers and chose the higher payment because I was told it included GAP coverage. A month later, I get my first bill not from Capital One, but from Santander. They switched the financing without telling me or getting my consent. At no point did I agree to Santander. This was a bait-and-switch, plain and simple. Completely unethical. I trusted the numbers I was given and was misled. Be careful if you finance through them, they do shady things behind your back.

This dealership is a scam factory, plain and simple.

This dealership is a scam factory, plain and simple. I came in with a legit pre-approval from Capital One, ready to buy. They ran my credit again without reason, handed me some handwritten “payment options,” and never said a word about switching my financing to Santander. I didn’t find out until the bill hit. That’s not a mistake it’s a setup. And after reading more reviews, it’s clear this is their playbook. Charging nearly $4,000 in surprise fees on used cars, lowballing trade-ins by $5,000, and jacking up the price on a Hummer EV order after two years with no shame. One guy said he left needing a shower, they’re that slimy. Buick GMC of Mahwah doesn’t just hustle they lie. This place runs on deception, and if you don’t walk in with your guard up, you’ll walk out robbed. Don’t say you weren’t warned

I had the worst time ever with Mahwah GMC Buick in buying

I had the worst time ever with Mahwah GMC Buick in buying a vehicle. I made an deposit and waited for recalls to be completed on a Toyota Tundra Platinum. I had to constantly contact the dealership for updates for weeks. Then because the Toyota was backed up on a motor replacement, I was contacted and told I needed to complete the sale or the vehicle was going to auction. OK, but I was told the recalls had to be completed before I could take possession. Because they were changing the plan, I was alarmed. Then telling me to buy it now or loose it, after I've been waiting and calling basically weekly, was threatening. So I booked a flight from SC to NY, got an Uber, and bought the vehicle. While making waiting for the detail to be completed (by the way the dealership knew I was coming and when) and doing the paperwork, I was left standing and ignored for the most part on 2hrs. This was likely because I expressed concerns to the general sales manager about how I was being treated...forced suddenly to move (pay in total in order to keep) after weeks for waiting patiently. Also, the general sales manager had to check with the Dealer Principal, Kathleen for clarity many times. Now finally seeing the Tundra for the first time, I discovered a deep key scratch going across the left doors to the bed. Next, the dealership had only one key fob. Now the great deal didn't seem so good. I was told when I pointed out the damage, that I should have noticed it in the picture. OK. I didn't expect it. By the was Kathleen walk in front of me and did even have the courtesy to say hello, knowing full well I had flown in from SC to completed the deal based on the previous day's call to me from the general sales manager (title?) threatening my purchase that I had been excited about getting once the work was done. So, I did it buy anyway. Drove it 11 hrs home. Took it to a Toyota dealership and got back in line for an engine recall. I also had their collision center give me an estimate for the deep scratch and the missing molding that say's Platinum. It was $3200. I also bought a key fog so I could have a 2nd key. It was about $450. Thank goodness the error codes check was good. I did have the the oil changed at this time, not trusting anything Mahwah told me. I want to forget I ever heard the name Mahwah. A day that should have been positively exciting was negatively anxious. I do not recommend this dealership. I even reached out to the founder and CEO via Linked In and received no reply. By the way I am definitely not a complainer nor hard to get along with. Quite the contrary, I'm very easy to deal with and soft spoken. You really have to provoke me to get me riled up. Congrats Mahwah GMC, you did it.
