Oil change
Social distancing, additional seating outside would be nice. Several of us just wondered the lot while waiting because there are only 2 benches.
2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

After entering my 2020 E450, I got a display message that said "12V Battery. See Operator's Manual". Sent a quick note to Mitch Griffin thinking after 5 years a new battery was probably needed. He responded and after contacting RBM, Jordin Mendez was dispatched to my house. In about 20 minutes, the battery was replaced. Great job by Mitch, Jordin and my phone contact at RBM. Much appreciated!

Outstanding buying experience with Drive a Dream.
Outstanding buying experience with Drive a Dream. After browsing the internet and looking for a car for weeks, I was so fortunate that I found my dream car - a 2023 Toyota Sequoia - online at Drive a Dream. However, being from Boca Raton, Florida, and being in the area for only one day - to visit my son at Emory - I needed to have a fast and seamless buying experience. Which is exactly what I had. In addition to a seamless buying experience, there are so many benefits to going to Drive a Dream to find the car you are looking for. Inventory There is huge inventory to choose from at Drive a Dream. Although Drive a Dream does specialize in high end luxury vehicles, you may find - as I did with my Sequoia - a car even if you are not looking in the high end space. Additionally, although many of the cars at Drive a Dream are not officially "new", they are basically new in the sense that they are all in excellent condition, many with low or little millage. In fact, the car of my dream - a 2023 Sequoia had a little over 10,000 miles and was basically new. Excellent Price: I found the vehicle I was looking for - a 2023 Sequoia - at an excellent price. So basically, I bought a new car at a discounted, used car price. Moreover, although not technically new, my vehicle is in excellent condition. Piece of Mind: Moreover, since my vehicle has approximately 10,000 miles and is only a year old, if anything were to go wrong, the manufacturer - Toyota - will cover the issue. However, I did purchase an additional warranty to provide me with more coverage at a nominal cost. Excellent Sales Associate: Steve Brant, my sales associate, was not only very friendly, but was also extremely professional and knowledgeable. Moreover, there was no sales pressure to purchase. Financing: The financing process was seamless and satisfying. The finance manager, Khalid Kanan who was extremely professional and knowledgeable, provided me with several options to choose from which would suit my budget. Buying Experience: My buying experience was outstanding and extremely extremely customer friendly. From the low/no pressure environment, to the speed of the transaction, as well shipping the vehicle to the location of your choice - at no cost. In fact, my family and I have purchased several cars in the last decade with Drive a Dream being the most satisfying. As mentioned, my sales associate, Steve Brant, was top notch. Moreover, Steve's coworker's from John his fellow associate to Basim Galla the General Manager, are extremely helpful and made the buying process extremely satisfying. I do wish I knew about Drive a Dream earlier so my wife and kids could have purchased their vehicles at Drive a Dream. Highly Recommend: In summation, I not only will purchase my next vehicle at Drive a Dream, but highly recommend anyone purchasing a vehicle to go there first. And if they are lucky enough to get Steve Brant to help them, as I was, they are in excellent hands.
