The service manager was outstanding.
The service manager was outstanding. He was involved in every aspect of my car repair. My issue was very difficult to diagnose. I observed him interacting positively with employees. I saw him doing manual labor, which you usually do not see. I was greeted positively from the moment I arrived. This is in contrast to the negative experience at AutoNation Chevrolet Pembroke Pines down the street from me. I know a positive business from the moment I walk in. I observe all employees including the amount of time spent with customers or just in the customer area. Happy employees are going to give customers a better experience.

I seen alot of negative reviews here and honestly dont know why!! They have been awesome to me and were very patient. I think maybe people are upset over their fees but no one works for free and the fees are listed... Worked with Brandon Martinez and it worked out great. Just be sure to do your homework first thats all and you will be 100% here. I also think their positive google reviews are more accurate than the cars.com comments tbh.

The other reviews here are penny ante, very minor stuff.
The other reviews here are penny ante, very minor stuff. I asked Lisandro for an out the door price and I got it fast, with options to help me with financing and shipping. Most other dealers are very slow and never give that price. Performance Mitsubishi's price was $12000 more than advertised. Give both a chance and you will do business with Lisandro. Spend a couple minutes and see. Besides being GREAT to deal with, test drive the Outlander. It drives better than the Rogue and is crazy cheaper than Toyota. It is nicer inside too. Don't buy a turbo gas car. They don't last as long. Buy an Outlander from Lisandro and you will get the deal and be happy with your car.

Response to my inquiry was prompt and courteous.
Response to my inquiry was prompt and courteous. So was the follow-up as the sales agent checked with me regularly. The initial internet presentation of the car wasn't great as pictures were of "other" cars of the wrong color, etc. I didn't buy the car so I don't know what happened after a few days.

That sounds like a truly fantastic car-buying experience!
That sounds like a truly fantastic car-buying experience! It's wonderful that you found a dealership that respects your time and knowledge. Here is a professionally rewritten version that maintains your genuine confidence and graciousness, perfect for a testimonial or review: 🌟 Highly Recommend AutoNation Ford Margate 🌟 After visiting three different dealerships, my experience at AutoNation Ford Margate stood out immediately, setting a new standard for customer service. I was impressed right from the start. I walked in, described the car I was looking for, and was instantly shown the Jeep Compass I had researched online, without any hesitation or manipulative tactics. This dealership clearly respects the customer's time. My salesman, Belin, was the definition of personal, professional, and sincere. He actively listened to my needs and knowledge. I was particularly impressed that he never once attempted to capitalize on the fact that I was a woman shopping alone. Belin earned my trust because his approach was honest and straightforward. There was no tiresome haggling needed—a welcome change from the "crap" I had dealt with elsewhere. Ultimately, I chose a beautiful, classy Black Mazda CX-5. The magic continued in the finance department with Scott. Despite my less-than-perfect credit, Scott legitimately worked the numbers to achieve a surprisingly low payment of $367. There were no fake fees, no hidden charges—just perfectly calculated figures, including oil changes and tire alignments for the term of the loan, along with Gap insurance. Considering the value, this result truly felt like magic. I left with my anxiety gone, completely comfortable and confident in the guidance and suggestions I received. My tank was full, my insurance was sorted with State Farm, and I drove away in my new car feeling empowered. The entire team approach is remarkable: • Belin: My sincere and professional salesman. • Scott: My financial advisor who delivered incredible results. • Matthew: The approachable Manager who genuinely ensures every customer's issue is proactively solved. I would highly recommend AutoNation Ford Margate to anyone purchasing a new or used car. I look forward to my next purchase here. — Stacy Gemini
