We sent a request to look at and drive the vehicle we
We sent a request to look at and drive the vehicle we selected and were contacted promptly by Fernando, a young salesman. Our whole experience with him was personable, professional and though. He is even going to contact the prior owner to secure a second key fob if possible. Our negotiations were very good. I did not feel I was being “high pressure “ or rushed to make a decision. Our requests were treated with respect and responded to likewise. I did feel that once we had settled on the final figures it took a long time to get back to the office to finalize signatures. But then there were a lot of others there as well… We were referred to Beaver Toyota by a friend and we are glad we went there. It was a good experience and I would encourage potential buyers to check them out.
This truck has a jerk when changing gears sometimes.

I had an amazing car buying experience with Sam at John
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!

I reached out to Platinum Cars Marietta about a BMW M850i
I reached out to Platinum Cars Marietta about a BMW M850i they had in their inventory, and I was thoroughly impressed with their professionalism and responsiveness. Jason Bush and David Patel promptly answered all my questions, providing clear and transparent details about the car and its pricing. Unfortunately, we couldn’t finalize the deal as the vehicle had a damaged part that they weren’t able to replace, but they did offer me a small discount to accommodate the issue, which I genuinely appreciated. However, since I’m investing over $50K in a car, I preferred to have it delivered fully fixed, so I decided to put the purchase on hold to explore other options. Despite this, I truly valued their transparency, urgency in addressing my concerns, and overall customer service. If you’re looking for a dealership that communicates well and is upfront about their inventory, I’d highly recommend Platinum Cars Marietta.

In-and-out, fast service & NO stress... THANK YOU!
I went to Carmax on 4th of July. The place was not super packed, so that was great. We had a little 9th month old on tow, and were nervous that it would take us all day to shop. The only thing that took a lot of time was waiting for a sales man. Apparently, the new young guys at the front were more interested in flirting (yes flirting) with each other and playing around than realizing that we needed help or just plainly asking us if we were being helped. That really bothered me, as we wasted 30 mins just sitting dumb. The front desk girl was no help.. she was the one to tell us to sit and wait and then no where to be seen. Finally someone professional and extremely courteous walked by ... the service manager. He quickly apologized for our wait, and brought along Daniel Claudio. I am SOOOOOOOOOOOooooO thankful he did. Danny was professional, kind, humble, hard-working, and just all the way a pleasure to work with. He represented Carmax the way it should be. He took the details of what we were looking for and walked us around to cars that would fit our needs. The second car (nissan pathfinder) was a recommendation from him... and that was the car we bought. Danny if you're reading this... THANK YOU! You're such a great employee and that deserves recognition.

I was in the market for a new car for over a year now.
I was in the market for a new car for over a year now. It is nerve wrecking and overwhelming. Decide to buy a new or used. I researched, test drive, and contacted over 20 dealers for information. Until I finally found the perfect car for me at the perfect price, while on the CarMax website in Norcross, GA. A 2023 Nissan Pathfinder SV 4WD with 16,500 miles. Practically brand new and at least under $2,000 and the lowest miles from similar vehicles in my area. One great thing about CarMax is that I was able to scheduled the test drive 7 days in advance. They reserved the car for me, no worries about being sold before my test drive. Another great thing about CarMax is the price advertised is the price you pay. Other than tax, title and registration, no other “bogus” fees are added to the price. I only wish they offered special incentives/discounts like military, first responders, student, etc. But, I am extremely happy with my purchase!!! Shout out to salesman Young!!! He is the first person I spoke to; he got the car for my test drive, and in less than 1-2hrs I was on my way home with a new car!!! In other words, DO YOUR RESEARCH!!!

Our 2013 Terrain was purchased from Colonial back in
Our 2013 Terrain was purchased from Colonial back in 2016. It has almost 222,000 miles on it. Still performing well. We always get great service at Colonial. Kimberly is our service representative. She does a great job. This time was a fluky thing. The only key we had was lost and we had to get a new set of keys. A frustrating situation was made easier with help from Colonial and Kimberly.

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
