James is a top-notch sales rep.
James is a top-notch sales rep. Contacted me quickly and processed my questions and requests efficiently. Will look to work with him in the future! A+
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.

Gianna was amazing!
Gianna was amazing! She did a wonderful job helping us find the perfect vehicle for us. I am so excited with my new car!

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!

Cameron has great customer care/service
Cameron at Larry miller ford was so kinda and made sure there was no funny business with the purchase of my new Bronco. I will definitely be buying all my vehicles from LHM Ford very happy!!
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!

I just recently had a divine experience at Mercedes-Benz
I just recently had a divine experience at Mercedes-Benz of Edison. Amir Brown was the light at the end of a very dark tunnel. I have never had a greater experience when shopping for a car in my entire life! He got me where I needed to be, and gave the best advice he could. What a great establishment that has wonderful employees like Amir Brown!
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.

Excellent experience at Dallas Lease Returns.
Excellent experience at Dallas Lease Returns. Chris Mikell was great to work with. The entire process was quick and with none of the stress or pressure that often accompanies car buying. I would definitely buy from this dealer again!
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.

I got a fair deal on a recent purchase. Working with Eric was a pleasure. I would shop there again.
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.

I recently purchased a Porsche Panamera Turbo S E-Hybrid
I recently purchased a Porsche Panamera Turbo S E-Hybrid from Universal Auto Group, and I couldn’t be more pleased with the experience. From start to finish, the process was smooth, professional, and stress-free. Baker in Sales and Jessica in Finance went above and beyond to make my sight-unseen purchase easy and comfortable. They answered all of my questions, handled the details with care, and even coordinated the transport of my new car to Florida. When the car arrived, it was exactly as described — no surprises, no issues, just the dream car I had hoped for. After a month of ownership, I can confidently say I made the right choice trusting Universal Auto Group with such an important purchase. If you’re considering buying from them, especially from a distance, I highly recommend it. Their professionalism, attention to detail, and commitment to customer service truly stand out.
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.

All we can say is.
All we can say is...WOW! Avi Hersh provided my wife & I with a professional, honest, great buying experience. The whole process was quick, and seamless. Avi was informative and took care of our car needs. The finance manager Bri Ables was also very polite and helpful with all finance needs. Would highly recommend buying from Mercedes Benz of xx. George. Thanks again!
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!
