Moe was an exceptional salesman. Although we decided to purchase elsewhere we highly recommend him. He was kind, straightforward and goof natured. He did not pressure us and was a great understanding listener.

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 treatment and exp I have had thanks to Scott
I have been going there for a long time now and as youngish woman who’s not rich - I can tell you I have always been treated with the utmost respect and courtesy! Scott had been my sales man and is great with his knowledge of the vehicles and explained how all the gadgets work and even went over and beyond for me! He communication is excellent and he is upfront and honest as it gets :) He work With my schedule and makes me feel at home while waiting on word from the bank. Scott always explained the paperwork and what it meant and why - which was so nice for him to take the time and do that with me. I have been to other dealerships years ago and most sales people Would Look at Me and see tomboy and think I’m not worth their time or effort and blow me off. Mike the financial guy was also great, he did his best for me & I know because I saw all the work he was doing and he explained things very well also. Especially with the extended warranty - Which is nice because some will just say “ call them yourself to see what’s covered on the vehicle “. They got me one that cover specifics that I needed for the future :) Lastly even when I would pop in to drop of papers or whatever reason- if Scott wasn't there, The other sales men still got my Questions answered and treated me very well. I would recommend anyone go there and they will have a better experience purchasing a vehicle then they have elsewhere and not feel ripped off …. Which we all know is nice - !! Thanks to all the people at Dave Taylor on Manchester rd - stl :)

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.
