This is the fourth vehicle that we've purchased from ELCO
This is the fourth vehicle that we've purchased from ELCO Chevrolet, and there is a reason that I returned for my third Tahoe: they're the very best. Three weeks ago, I lost my husband unexpectedly and with two ELCO Chevy's, one 10 yr old Tahoe and a two-year-old Trailblazer that my children didn't want I felt it best to combine the trade-ins and purchase a new Tahoe that will take me another 10 years, providing me not only transportation but the security I need moving forward. The staff at ELCO were respectful, kind, understanding, and efficient. The purchasing experience was excellent from start to finish, and they took every step to make me feel like I was the only person in the dealership those two days. I am very grateful to Mark Gerecke and Branden Nehls for all they did to make the process as easy and comforting as possible given the circumstances. I am an ELCO customer for life.
Best Car I've Owned
Dollar for dollar this is the best car that money can buy. A 3 year old MB Certified car with around 30,000 miles is the way to go. The price will be about 50% of original MSRP so you save about $50,000. I suggest 4 MATIC and AMG trim package. I 've owned other MB's, high end Jaguars, BMW's, Volvo's, VW's and several American cars, new and used. This is the best.

Great staff!
I found the exact car I was searching for and this dealership was above my expectations during the buying process.
Amazing vehicle, but only buy new if you want the S63,
Amazing vehicle, but only buy new if you want the S63, the Maybach, or your just really rich, if not, then just wait 5 years, and get it for 70 grand! The value is so low because you can just wait for it to depreciate like crazy. But overall, this is an awesome car.

I have purchased a few cars from Mercedes Benz of STL
I have purchased a few cars from Mercedes Benz of STL over the years. Most recently last week bought AMG GLC 63E S working with Scott Gilbert. The experience was fast, smooth and got us going on our way same afternoon. Scott followed up with me a few times since to make sure everything was in order and we couldn't be happier
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 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 recommend Mercedes Benz at Maitland, FL.
It was a great experience buying mt car at the dealership. The look and features of the car is what attracted me to it. Donte is a great salesman, he is very knowledgeable. He answered all my questions and show me how to use all the features that the car has.

Mr. William took pride in doing every thing he said when l came in to pick up the car their were so issues so I was having some problems accessing the issues Mr. William took great care of me and my problems that put me in the car of my choosing.
I’ve had many Mercedes-Benz models over the years,
I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

BEST CAR WHAT WE HAD !!! It is solidly built, quiet, and smooth. I'm a big guy, 6'3" and big-boned, with two younger children that require car seats. There is still some room behind me with the seat backed up all of the way. The features and smart key are a nice touch.

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!
Traded it in after 19,000 miles
I traded mine in after 19000 miles for one reason, the run flat tires. they are $300 a piece and last 15000 miles. They might be an option, if you don’t mind putting new and expensive tires on every year but they don’t perform in snow after 5000. They don’t perform great when new to be honest, just better in snow with more tread. I loved the car, but living in hilly, snowy Pennsylvania, it just wasn’t practical. Think twice if you drive in snow or rough roads or just don’t feel like getting new expensive tires every year
