Pay attention what get in your hands paperwork throughly
Pay attention what get in your hands paperwork throughly read it carefully and see everything they put in it such extra extra cash that you didn’t say and extra money makes it go up higher that you can’t afford the extra payment.Now you see how much gap insurance $$$ added in the paperwork and makes sure you get a lawyer go with you when getting used filthy car full of dog hairs.Makes sure you have mechanic on hand too.They will sell you a car without license which is illegal.Don’t use no co-signer.Don’t use Ally financing on new or used vehicles.Even if you pay it off tell you getting gap refunds on mailing letter.they will keep it cause you don’t qualify for it.Keep up with all your paperwork in a file and payment history on papers like print out.Get your payment down as low as you can and 84 months is long ways to go.Do research how to save money on used or newer car without all that crazy extra add on.They’re trying make money of of you even on the elderly people.Have a great day everyone

Great dealer for your custom order!
Worked with Ced Thatch in Sales on a truck order. Although I was unable to purchase due to my financial situation he was great to deal with through the whole process. The ordering process was quick and easy. Pricing was very good and my sales rep was very responsive throughout the wait anytime I had any questions. I would definitely recommend if you are looking to order a truck or SUV even from out of state. This is a big dealer with lots to choose from and a solid office team to help with your purchase.

I found my car on the internet and scheduled a test drive
I found my car on the internet and scheduled a test drive with Kiara. I was her first potential customer. She did a great job even though I might have scared her on the test drive. I ended up coming back after I sold my truck and was able to work a fair deal after some good negotiations. Part of my negotiation was to bring my car back and have a few things fixed on the car that I wasn’t happy about. After about a week, I was able to bring my car back down to drop off for a few days while the work was being done. I worked with their finance guy Keon. He lined me up a loaner to drive while they had my car. After about three days, the work was done and I went to pick my car up. I was very pleased with the outcome and they even fixed a few other things that we didn’t agree on but new I had questions about. They listened to me as a buyer and were willing to work with me. If you want to avoid big dealerships, they have a great inventory up nicer cars and are great to work with. I will shop with them again!

Ayy, real talk — I pulled up thinkin’ this was gon’ be
Ayy, real talk — I pulled up thinkin’ this was gon’ be the usual runaround at the dealership. But then I linked with Manny Platero, and everything switched up. Bro came correct, handled his business, and treated me like a VIP from the jump. Wasn’t no gimmicks, no fake “lemme see what I can do” type vibe. Just solid service, real communication, and straight-up respect. He told me what the car needed, kept it 100 the whole time, and didn’t try to finesse me on no extra charges. That’s the type of professionalism you don’t see enough of — especially in this game. Time is money, and Manny respected both. That’s Atlanta energy — hustle smart, keep it real, and treat folks right. So if you in the city or even just passin’ through, and your ride need love — go ask for Manny Platero. He ain’t just a service advisor, he a real one. Salute from the 404.

Jimi Mingo is an awesome sales person.
Jimi Mingo is an awesome sales person. There were some pricing issues relating to the list price and addendum items were added but not disclosed with the window sticker. The list price was honored. Also was low balled on my trade and had to go to CarMax to get an independent appraisal. My trade was never inspected by Mini.
