Great dealership.
Great dealership. Being a out of state purchase. Scott Gilbert was very helpful made everything smooth and easy and simple. I recommended Scott to anyone looking for a vehicle. Also Steve in finance made all the paper easy. They sent paperwork overnight with a over night return envelope. The whole process was smooth and simple. Thank you will use you guys again in the future.
I love my GLE
Very smooth ride. Lots of cool safety features. Good power. Good value for my money as I bought this as a CPO. Mercedes Benz financing made it easy to own.

John was very helpful and ensured this was a smooth and enjoyable process for a first time buyer!
This is our second GLC 300.
This is our second GLC 300. We love the size and features for our needs (two people). Good mileage 27-29+ around town, 30-32 highway. Smooth ride, easy handling, and I think, nice styling. Newer models have larger screen and are more electronically controlled from the screen. Fields of Orange Park, Fl. has great Service, not cheap, "Mercedes" nuff said, but they will take care of you.

Great experience purchasing our new car from Lesa at MB
Great experience purchasing our new car from Lesa at MB St Louis! She is so thoughtful ans thorough and keeps her clients well informed throughout the car buying process. She made sure to answer all questions and made it so easy. She is approachable and made sure all our questions were answered. The whole dealership has been excellent. We are leaving audi after 15 years and are so happy to find the perfect Mercedes with Lesa at your dealership! Thank you so much.
Great Car Sorry Dealerships
Great car, terrible dealers and maintenance costs. I have had two GLA vehicles, a 2016 GLA45 AMG and this one a 2018 GLA 250 AWD. I have a love-hate relationship. The car itself is really enjoyable and the 208hp dual clutch drive train is nearly perfect in my mind for sporty but efficient driving. It has good acceleration, little to no lag and I can consistently hit the high 30’s for mileage in the mountains of Colorado. I have gotten 38mpg over a 250 mile trip. It is mid 20’s around town which is good because you need premium gas. The storage areas are small-ish and funky but doable and has two USB ports in the center console with no grooves for the cables but they will pass through. I recommend blind spot detection as a must because the side mirrors have a large blind spot you cannot dial out. The car runs very smoothly, absorbs bumps well and decent sound proofing for this size. The power lift gates, keyless doors on all four doors just touching the handles is perhaps my favorite comfort feature. It drives like a car so if you like high SUV seating positions this is not for you. Air works great, electronics are kind of odd for 2018 so having Apple Car Play is a must in my mind if you are buying used. I really love the car for it’s details, lovely interior and performance and can recommend it to others based on those things. The huge negative for Mercedes is they are hands down the worst dealerships and I interacted with three. They do all the classic dealer tricks and the maintenance costs on a car running perfectly fine will make you bleed. An A service (odd years) was $933.00 and they wisely will not tell you that till you show up. Shop around as another dealer was only about 60% of that. I just replaced a dead battery today and it was $639.00 and done in less than an hour. I would go to an independent shop for half price maintenance unless a warranty item (I have extended/CPO). In the end this makes me give up on Mercedes. Cars are wonderfully engineered and truly enjoyable and look great but dealers and everything associated suck. Yeah, I know there are probably good ones and if you don’t mind a siphon in your wallet and typical dealer tricks then you will love them and they will love you. So, 100% recommend the car and a 100% thumbs down on the dealers. Research yours carefully and if good or if you can go to an independent then jump on the car if you like sporty, elegant and fun.

Best vehicle badge to own.
Bought this 9/2020. Looked high and low. Found it at a large well known dealership.It was a low milage lease turn in they bought at auction.Excellent vehicle.We have owned Mercedes for 40 years. Always gotten good service from them. An average of 10 years per car. Saved some 2K after reading many "how to buy" on you tube. Rehearse ,rehearse your approach and how to deal with the seller, its worth it. Only drawback is no spare. I bought one and dumped the "run flat" tires- very harsh ride with them.

It’s the bomb
I bought my 2007 SLK 280 used in 2022. I had it inspected and knew ahead of time I was going to have to put another $5k into it to make it right and how I wanted. So far I’m very happy with the car and am glad I spent the money. Great combination of being sporty, luxurious and roomy. I initially was considering buying a used Porsche Boxster but I’m 6’4” and it was too cramped and the interior looked and felt cheap to me. My SLK just looks and feels very high quality and it is so much fun to drive. I put in an upgraded radio with touch screen, usb, CarPlay etc. made in China that was made to match the existing accessories (highly recommend). The car is in such good condition people think it’s new. I’m always looking for excuses to drive it and can’t wait to get in it. It has a top speed of 155. I have had it up to 130 and it’s solid as a rock. The Germans make their cars autobahn ready.

Best salesman EVER
Thomas Grice was a great salesman. He explained the car details so well that I feel VERY comfortable taking the car home (190 miles away)!! I would suggest he is the best car salesman I’ve experienced in the 7 new cars I’ve purchased and too many to count used cars my late husband and I bought. Very professional!
The features are amazing,stylish .
Great driving comfort,loaded with features. Safety is definitely a priority with the MB engineering . I have leased a total of 4 Mercedes and totally satisfied with every single one.

Loyal customers
We recently purchased a certified pre-owned vehicle at Frank Leta Acura and this is our second purchase with the dealership. Each time we’ve received excellent customer service. Kevin Baker was our Product Specialist that helped us with our second purchase and was very instrumental in finding us the right vehicle with the options we were looking for. He was very good with follow up and keeping us updated on our vehicle. We’re really happy with our purchase and the services that we received at Frank Leta Acura!
Most reliable and usefull car I've had as a daily driver.
Most reliable and usefull car I've had as a daily driver. Everything in the interior is placed where it should be found functionally. Power, while not a muscle car, is more than adequate. Gas mileage is excellent. Adjusting from Comfort to Sport make a very noticeable impact on the driving experience from gear shifting to steering...

New to Mercedes Family
I have driven only American cars since 2006, they normally come with lots of bells and whistles, so it was funny to see an ash tray and CD player in the vehicle. I like the way the car handles. It is smooth to drive and comfortable. Not too big and not too small.

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

Jennifer Crawford Was The Best!!!
My experience with this dealership was nothing less than wonderful. The entire sales department was nice and respectful. Sales and leasing consultant Jennifer Crawford was the best from the very moment I pulled up to the lot. She’s a sweetheart and made the process so much easier. She went above and beyond to make sure that I was satisfied. I’ll recommend everyone to her from this day forward!!!
Best Mercedes for the value!
I love my 300C with the AMG Package. You get a much sportier look and drive. The car rides very comfortably in Comfort Plus but you can put it in Sports Plus and it becomes a whole different car. It feels like the car stiffens up and the Torque is immediately right there. Also, the AMG Package comes with great brakes! At this price point, you're going to hear a slight wind noise at higher speeds and the back seats don't have a lot of legroom. But, as an entry-level Mercedes, this is the best Mercedes for value in my opinion.
