Hello, We search several dealerships for a car,
Hello, We search several dealerships for a car, specifically a Mercedes. My son found an excellent dealership, Ride-N-Drive, in Garland, TX, -- his "dream car," he said. The place is small/nice & the staff are friendly, inclusive of a diverse collection of great cars. *** Thank you, Shane, for the favorable experience. Your professionalism and patience are first-rate. We will send referrals on your way. Thanks to Anthony for helping us finalize the purchase yesterday (4/25/25) Ride-N-Drive exceeded our expectations. Awesome service! ****Highly recommended. Friends, give it a try, and you will be happy with the service. ******** Ask for Shane Swenson. -Have a fantastic day! Ami
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Jupiter Chevy Rocks
In and out in 1 hour on a Saturday, for an oil chage and inspection, and on short notice. Good job Jupiter.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I recently purchased a 2020 Mercedes G550 from Top Line
I recently purchased a 2020 Mercedes G550 from Top Line Auto, and I couldn’t be happier! The car is absolutely phenomenal—every detail exceeds my expectations. The service I received was exceptional, going above and beyond to ensure a seamless experience. If you’re in the market for a vehicle, I highly recommend Top Line Auto. They truly deliver excellence in both cars and customer care!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Love me some Five Star Ford!
My wife's 2017 Edge Titanium needed service because the "wrench" light came on. Dropped it off and met with Odie Terry, our Service Advisor. Odie informed us that it will be a day or 2 before a tech could get to it because they are always so busy. Odie called me a couple of days later and said the battery wasn't getting enough volts to the sensors, creating numerous error codes. Replaced the battery and one code came back as a torque converter issue. Once we found out they would be keeping it awhile Odie arranged a rental car for us. Turns out the transmission needed a complete overhaul. Thank God for the 5 year/60k mile power train warranty, which covered everything! Took about a week but once we got it back it drove like a dream! Odie called me every 2 days to give me a progress report. He made what was a major inconvenience much more bearable. It's nice to know there's a dealership close to us we can totally trust to service our Edge and do everything right. Hats off to you Odie Terry, you are a true professional and an outstanding ambassador to the Ford Motor Company!

Great Service!!!!!
I truly enjoyed my shopping experience yesterday on Friday. October 2, 2015. Mia was very patient, professional, and caring in listening to my needs and concerns. With God's and Mia's help I was able to purchase a 2015 Ford Focus. Thank you again Mia for being an excellent salesperson. I will definitely recommend CarMax to my friends.

Same old car dealer tricks
Update, I was quickly contacted by the GM who promised to make good on the car by either getting rid of the smell or take the car back.
