Steve Grossman made me happy
I had an issue with my Rolls Royce and was not happy. Steve Grossman stepped in and after a few days he made me very happy and really took care of me. As a former dealer and Auto executive Steve Grossman did a great job. I recommend the Veanan group in West Palm
Very Happy with SL450
Recently traded a 2019 Corvette Z06 for this 2020 SL450. The Mercedes is much quieter and rides better. Quality and fun factor is high. Mercedes infotainment system and menus needs to be more user friendly.

I do not provide feedback to anyone unless the experience
I do not provide feedback to anyone unless the experience was excellent (Prior bad experiences). My experience at Napleton was excellent! Jessica, Brian and Julian were friendly, personable and yet professional. Email responses were timely and addressed any concerns or questions I had. The ppf was a late minute addition that was quickly addressed so that the car could be picked up on schedule. The car was prepared and detailed, looked new (CPO). The hospitality was very accommodating. The show room was filled with some really impressive cars. Overall a I left with a very satisfying experience and would recommend this dealership to anyone.
An amazing V6 Grand Tourer!
Excellent performing V6. And I say this after having owned an AMG SLK, an SL500 and an SL550. This one handles better than any of those 3, is an excellent performer (albeit, of course, not quite as fast as the SL550) and don't be turned-off by Mercedes typical conservative performance stats. Road and Track's are far more accurate: "0-60 in 4.5 seconds; and 107MPH in the standing quarter." Then compare it cost-wise to the price of an SL550 identically equipped (V8 excepted) it's more than $18,000 less costly. All-in-all, an EASY and wise choice. Fine GT car!

Awesome Mercedes 450sl
I have owned a Ferrari and 2 Porsche models as well as numerous BMW. The 450SL is in many respects all of them wrapped into a a tidy wonderful car. There is nothing not like in this beautifully designed 2 seater.

New 2018 SL450
Very happy with the '17 to date refresh of the R231 SL series. The new front facial treatment is much more sleek and balanced that the original take from the 2013 entry. New 9 speed transmission is so smooth you think it is a one speed.

From the moment we walked in and met with Jimmy service
From the moment we walked in and met with Jimmy service was first class. He provided information, and showed us patience and professionalism. When other information was needed he quickly brought in Dina with education and Andrew from finance. Jimmy was kind, professional and ensured time was taken to make us feel comfortable and welcomed - BRAVO on the first class experience!
One minor issue that was addressed and resolved.
Great GT. Very comfortable. Excellent performance. Super good looking. Would buy again. Is the 3rd SL we've owned and, is likely, THE best one of all. Doesn't have that V8 sound but at $20K less in price, we'll accept that . . . in a heartbeat! I.e. 0-60 in 4.5 seconds and 107 MPH in the standing 1/4 mile is plenty quick enough!

Fabulous and off the scale honest
I traded in a 6 month old Lexus hybrid for a Mitsibushi lancer. I paid $20k for the lexus and my 16 year old pretended to like it but he hated it. It was a lame hybrid and his friends laughed at him. So before he even got his license and had only added 400 miles to the car I took it back. Eliot got me a deal on a Mitsibushi with 19,000 miles. The trade in came back at $14,000. Eliot WENT BACK AND GOT ME A BETTER DEAL! because I was a previous Carmax customer. I ended up with a 5 year warranty on the Mitsubishi and a $700 refund... You cannot beat Carmax. If you buy cars from this dealership THEY LOOK AFTER YOU. Genuine customer.
Great car, but short on some deliverables
I like this car. My first sl500, ten years ago, was better in my opinion. The 2019 has beautiful inside styling and very comfortable. Technology does not match my Audi Q8 SUV. Very advanced, SL450 not so much. Not bad, but not up to snuff compared to others. Some features hard to use. Mercedes has never produced a very workable Navigation system. it's old and awkward and voice control is a total pain. Overall, I'm a fan of the car, but it is overpriced for what you get in my opinion. I liked my 2017 CLS 500 much better and now, with the 2019 style changes making it look like a 30k C Class, won' buy that one anymore. I've been driving Mercedes exclusively for my regular care since the 90's. Overall very happy. Seems like now though the prices are up but the technology and even style is not keeping pace.

Dimitry was great in the whole process. He answered all of our questions and was very helpful. We ended up buying two cars for our boys. I would totally recommend him!
Awesome Vehicle - You Stand OUT!
The craftmanship and accessories are beyond what you are used to in other vehicles. Truly luxurious! Great Ride! Great acceleration and stopping! This is truly a very unique auto - in my opinion the BEST hardtop convertible on the market - and I've driven many.

Genuine Motorcars, Inc.
Genuine Motorcars, Inc. is a treasure for individuals looking for exceptional luxury, collector and sports cars. Jim, the owner, and the sales rep, Eric, both are low-key, knowledgeable and likeable guys who are real "car guys". It's worth a trip just to meet them and enjoy the remarkable inventory.
Have only had it a day, but it's wonderful.
This is head and shoulders the most comfortable car I've ever driven. Favorite things: * Convertable-ness * Magic sky * Seat bolsters * Massaging seats * The way it feels cornering * The throaty exhaust

Fast, Friendly, and Helpful
I saw a 2014 Silverado LTZ that had all the features I had been looking for. I set my mind to drive up and look at the truck (I opted not to transfer as I had family in the area I intended to visit). The hold process is GREAT. It's a quick click and I knew the vehicle was going to be there after I drove the 3 hours to look at it. I worked with Chris Biggs and he was great. We talked options on the truck and for financing (they beat my credit union's offer). He was incredibly friendly to be around and my wife and I thoroughly enjoyed talking to him as we waited on our financing offers. He was thorough in making sure we had all the facts and options. If I had anyone in the area looking to buy, I would send them to Chris in a heartbeat. Then I know they'd have a good experience and be completely taken care of.
beautiful
I love my car! The navigation is poor and I always use my iphone. That is my major complaint. I love how it hugs me on curves. Trunk space is very adequate and ro0omy for a sports car!

I recently purchased a preowned car and couldn’t be happier with the experience! Drew and his team were incredibly transparent, answering all my questions and providing detailed information about the car’s history. They made sure everything was in top shape before handing over the keys, which gave me a lot of confidence in my purchase. It’s rare to find such honesty and dedication to customer satisfaction. I’d highly recommend this dealership to anyone looking for a trustworthy place to buy a used vehicle!
Timeless roadster
Great car. Never in for service except routine maintenance. Gets looks and compliments everywhere. Great commuter car and weekend car all wrapped in one. If you own one, you’ll own two.

David and Joel were great.
David and Joel were great. It was the first time buying a car from a dealership in another state and it was something I swore I would never do without physically being in person to see a car. But right off the bat David put me at ease by accommodating my requests. The car was exactly as David said it would be. I have to give props to Joel as well he found me a good finance rate and had all the paperwork ready when I arrived. When I’m In the market to buy another car I will Definitely be hitting up David and Joel.

No pressure No games Easy buy of a cash car.
I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.

I have bought three cars from them easy to work with there vehicles are always in top shape never had a problem with them at all Garrett took care of everything
actually it's a 2017 with 9K miles
great combination of luxury and sportiness. drives like a 2 seat sports car when top down, or a comfortable sedan with top up. great acceleration for a 6 cyl. pricey but well worth it. fills a unique niche with little competition.
