I was very happy with my time dealing with Charles. He had the truck I wanted to test drive ready before I arrived at the dealership. I felt like family. Charles was very, very patient with me the whole time.
This truck has a jerk when changing gears sometimes.

Lemme tell you about them
Lemme tell you about this dealership. This was THE easiest and fastest deal I have ever experienced. Bob Chitwood is the truth. I met with him on a Saturday for a test drive. By Tuesday I drove away with my new car. He handled everything little detail BEFORE I arrived to sign all of the paperwork. Everyone was super nice, knowledgeable and relaxed. Would I buy another car from them, yes. Is Bob Chitwood a thoroughly great salesman? Yes!!! He was soooooo good at his job, my bestie-who was with me for the test drive -also drove off the lot with a new car. Love. Them.

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 :)

Overall good drove over three hours to arrive, pain that
Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.

Great Service!!
I was looking at buying a 2014 Toyota Corolla and Willie was the 1st person I talked to at the dealership. There was absolutely no pressure from the start of the conversation to even buy the vehicle. Before we even talked about anything sales wise he recommended that I take a look at the car and test drive it before anything to make sure it was everything I wanted. Even during the test drive, we didn't talk about buying the car, it was just a normal conversion. After test driving the vehicle I needed to think about it and even then Willie never tried to keep me at the dealership to try and buy the car. He followed up with me a few days later to see how everything was going and even put the car on hold for me so no one else would take it/buy it. I ended up not buying the vehicle this time, after thinking about it for a few days. The customer service I received and the atmosphere that, i'd have to say Willie created, was Fantastic and would highly recommend asking for him if you are looking for a car. I couldn't be more satisfied with the service I received, and will be going back to him towards the end of the year to then purchase a vehicle.

So easy, Emily is the Bomb
I always dread the car buying process, it’s long and you need to play the game. But Emily listened to my wants and needs. Honored my wishes on certain cars. She worked for me not for what the finance company wanted. Thanks Emily!! For the easiest car buying experience ever!
