Go to BMW of Freeport...
Our experience at BMW of Freeport was great! We are first time customers and our experience couldn't have been better! Marleny was wonderful! She was with us through the process from inquiring about our car until we drove off the lot! She knows her vehicles! Everyone at BMW Freeport made this an enjoyable experience. I would recommend Marleny and BMW of Freeport!
Very nice upscale vehicle. Bought as a previously
Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

Fantastic Experience!
Had a pleasure doing business with Russell Westbrook CDJR for my new 2021 Dodge Challenger! Zaman, Moses, and Jay worked with me tirelessly to make sure I was happy with the car and our deal for it. This is the second vehicle I've bought from them and I'll definitely be back for a third in the future. Highly recommended!
Beautiful Meh
Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.

Matt and the used dealership was great.
Matt and the used dealership was great. We talked via the phone and had everything prep and ready to go. The warranty guy, not so much. He was very pushy on a extended warranty after being told no 3-4 times. The only reason I deducted a star. We picked up a RX350 and was great process.
best of 9 audis i have owned
This is the most advanced designed Audi I have owned. It is a comfortable,quiet & a beautiful handling vehicle. Loaded with safety features. Love the driving experience.

The experience was good.
The experience was good. The sales lady called me immediately and sent video of the truck since there were no pictures on line. I made the request Saturday night Amarie called me Monday morning I went in to view the truck and did a test drive on Tuesday and made the purchase.
Just purchased
I originally owned an Audi A4, which was an excellent vehicle, very reliable. I expect no less from the A6, which offers all the latest in safety and convenience options. So far I am very pleased with the car and I am only scratching the features it offers. Great ride.

Love this car!
Got the premium plus with Executive pkg, black optic and V6. Love this car! Only had it a week, but happy with the purchase. Was originally looking at Mercedes as I had one for 13 years, prior to my Jeep. Price and drivability was superior with the Audi for all the features I wanted.

I had an amazing experience purchasing my Tesla at North Bay Imports, and I can’t thank Jackson enough for his outstanding service! From the moment I walked in, he was professional, knowledgeable, and genuinely committed to making the process smooth and stress-free. He answered all my questions with patience, guided me through every step, and ensured I drove away feeling confident in my purchase. If you’re looking for top-notch customer service and a seamless car-buying experience, I highly recommend Jackson and the team at North Bay Imports

scoured the internet for 2 years to locate the car that I wanted. Kian motors had the car in their inventory. I took a chance and called Layne Elrod at Kian Motors. Right from the onset he treated me as a close friend and not as a salesman. He made sure every question I had was answered to my satisfaction. He was not pushy but wanted to make sure that I got the right car for the right price. The process of buying my car, having it shipped from Texas to Florida, and finalizing the paperwork and payment was very smooth. all because of Layne Elrod. I have seven daughters and when it comes time for their purchase, they will be calling Layne Elrod at Kian Motors first. All the way a pleasurable and stress free experience.

We were happy here.
We found a car we liked online and went and looked. We were able to take the car for a test drive, the price matched what we had in mind, so we bought it. We had pre-approved financing through USAA, so that made it even easier. We'll be back.

Steve was very welcoming and knowledgeable. The whole team was organized and friendly. Smooth and quick! I would recommend this team. They did not try to sell me a bunch of silly overpriced warranties or Underbody rust proofing. They respected my time and my intelligence, and I appreciate that. I will buy from them again:)

Exceptional Service and Dedication at DARCARS Lexus of
Exceptional Service and Dedication at DARCARS Lexus of Greenwich! I recently purchased a car from DARCARS Lexus of Greenwich, and I can’t speak highly enough about the exceptional service I received. From the moment I arrived, the team made me feel valued and ensured every detail was handled with care. A special thank you to Brooke Jessup-Labonte, who truly went the extra mile—literally. When I decided to sell my old car through CarMax, Brooke offered to drive it back to my home, spending over several hours in unexpected heavy traffic. When an issue arose with the payoff information, he handled it seamlessly, contacting the dealership and Toyota to resolve everything on the spot. His kindness, patience, and professionalism left a lasting impression. I also want to recognize the incredible teamwork of Dave Miller (Manager), Andreas Tsirikos (GM), and Michael Tuzzio (Manager). Together, they made what is often a stressful process feel smooth, efficient, and even enjoyable. I’m absolutely thrilled with my new car—a Lexus that I instantly fell in love with during my visit. It’s a perfect fit for my needs, and I’m grateful to the team for helping make it happen. If you’re looking for a dealership that values its customers, provides impeccable service, and goes above and beyond, I highly recommend DARCARS Lexus of Greenwich. Their dedication and care made this an unforgettable experience, and I wouldn’t hesitate to recommend them to friends and family.

Bought 2 Cars Here, Now Going Back
Bought a car here. After several years I traded it in and bought another. Values were fair on my trade-ins. Vehicles on the website are really the ones they have on the lot. No pressure, no negotiating, huge selection. Paperwork process like normal. I did have to refinance after I left there because the interest rates were steep and I got better deal from credit union. Overall recommend. Had a car accident, will return to Carmax.
