2022 F150 from Cook Ford
I?m not one to leave reviews online when I have bad experiences , non the less when I have a good one BUT I really feel my experience at Cook Ford and giving appreciation to Eric Osorio(sell?s guy) and Tania Brown(finance manager) is well worth what little time I have to get on here and leave them a review. I bought my 2022 F150 on Nov 22nd just before Thanksgiving. I?m a man of little free time when I?m off work and was in somewhat desperate need of a truck. With thanksgiving being only 2 days away I was stressed enough not knowing if I?d be home for the holiday or stuck on a train at work so I had that to add on to my stress. Just as I pulled into the parking lot rain started to pour down. I took that as a bad luck sign. I felt as if I was going to walk into the dealer and be rushed,forced and pressured into buying something I didn?t really want at a price I felt was over priced. Eric Osorio made me feel the complete opposite of that. I didn?t go in with a certain truck in mind,I just knew I needed one. Rain was still pouring and he did not hesitate one bit to go outside in the pouring rain and walk the whole lot with me till I found the truck I wanted. Never complained about the rain nor made any bothered faces about me taking my time to look at their inventory. So we walk back in and start discussing numbers as well as a vehicle trade in as I was going to trade in a Ford Explorer I had. Was nervous because I never traded a vehicle in. He made the whole process seem like a walk in the park and was able to work with the Cook Ford manager on giving me a better offer for my Explorer than I had in mind. Everything just seemed like it was going too good based on my passed experience at a previous Ford dealer back in 2019. Across the hall from Eric was the Finance Manager (Tania Brown). She was previously helping out another client as Eric was wrapping up all the paperwork I needed to sign. As Eric was finishing I could see a young lady in her early 20?s with her mom walking out Tania?s office with a big smile. That gave me somewhat of a stress reliever. Just as Eric introduces me to Tania and it?s my turn to walk in and go through the final finance process with Tania her lunch was getting delivered via grubhub. Being that I spend a lot of time away from home and don?t really get to sit down with my family at the dinner table every day/night Breakfast,Lunch and Dinner time is sacred to me when I am home with my wife and son of 2yrs old. So I told Tania that I didn?t mind waiting outside while she ate her hot meal that had just been delivered. She told me it was fine and that she could wait till she got done with me. This made me feel like now she was going to rush me out of there and not give me the same impeccable service I received from Eric Osorio so I told her once more that I didn?t mind waiting but she insisted in helping me still. To my surprise miss Tania Brown made me feel just as comfortable as when I was dealing with Eric. She didn?t try to force me into getting anything I wasn?t really looking for in a warranty package. To be honest the price of the truck and monthly payment I was going to have was a bit more than I wanted but they were both able to give me a good deal on my trade in,new truck price and final financing. So much so that I was able to walk out with just the monthly payment and overall final financing price I was hoping for. Tania Brown really helped ALOT with getting me the perfect balance of warranty protection for my new truck. She was such a kind hearted person that I even shaved personally family business with her(in a good way,no negative stuff)and that?s something I don?t do even with my close friends. She even shared information about programs and events that will be fun and helpful to my wife,son and I. I drove in on a rainy day and gut feeling of bad luck and drove out feeling as if I just left Sunday service. I can?t help but say that Eric and Tania?s teamwork was top tier and 2nd to none! TY!

Good service and help at Ron Carter.
Misa was very professional and helped me to get the auto I wanted. He was very helpful 👍 my Gladiator came in as ordered. Misa kept me “in the know” regarding status of my incoming vehicle. I would recommend others to use him as their sales person. I have already recommended Misa as a sales contact. The overall dealer appears to be well ran.

I'm very pleased with this dealership.
I'm very pleased with this dealership. Top-notch service, friendly staff, quality vehicles, and a great level of personalized service. Rudy was the best salesman I've worked with, and this is the 7th car I've bought in my many years driving. I'm really impressed with the automobile I bought and with the price. Truly a no-haggle and no-hassle deal. Hamida made the financing paperwork easy and quick. I've already recommended them to two coworkers and I will be shopping for my next vehicle here too. Thank you again Rudy!

it was time for my annual check up and stop by to see my salesman, Brad Biondo, who had emailed me an assessment of my 2020 GLC. I was just there to say hi but I left with a 2026; Ha- that wasn’t the plan. I am so impressed with the upgrade in terms of performance and attributes. Brad is super knowledgeable, reliable, and has integrity. Overall it was a fair trade.

I had a great experience purchasing my 2026 GMC Canyon
I had a great experience purchasing my 2026 GMC Canyon AT4 from Group 1 Buick GMC South. The process was straightforward and transparent, which I really appreciated. Jazmin was professional, responsive, and easy to work with from start to finish. We agreed on a fair out-the-door price in advance, and that price was honored exactly as discussed. The team was patient with my questions and never made me feel rushed. Overall, it was a smooth and respectful buying experience ? no pressure, just clear communication and follow-through. I?d definitely recommend this dealership to anyone looking for a straightforward car-buying process.
