Dvonte Muhammad reach out to me & his manager helped me get my credit and truck fast very friendly as well . Definitely recommended
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.

Easy Buying Overall
Courage did an excellent job in the sales experience for the Porsche Cayenne we bought. The only complaint I have is the wait time for the financing to go through. This was due to the fact that it was a 2014 model. But, again, financing experience at any dealer has never been better or worse.
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.

Awesome Buying Experience
My sales associate, Brian Safianow , could not have been nicer. He was a great listener and quickly assessed my needs. Dealership manager, Gary Venner, was involved in the process. The entire process was painless, fun and Brian provided concierge level customer service. Additionally, the technology department came to my home to provide a thorough tutorial on the different features of the vehicle. I am very pleased with the car,its many features and that subliminal new car smell. Park Place Lexus Grapevine treats their customers like royalty! This is my third experience with them, and I highly recommend them for the personalized, professional and exceptional service that they provide.
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

The best way to buy a truck!
If you want to sit around all day, haggle for a price, have someone go back and forth and talk to “the boss,” and generally have an all-around traditional car buying experience, this dealer is NOT the place for you! These guys have a niche and they know their stuff; you’re not going to get the run-around here because their prices are already competitive. My salesman, Anthony, was fantastic as was Jeremy, the finance manager. If I hadn’t sat around and visited with them both, I could’ve been in and out in an hour. This is how buying a vehicle ought to be.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Repairs Exceeded expectations
Repaired our VW air conditioning unit in three days. Another dealership failed to repair it in three attempts covering a period of over a month. Clay Cooley was courteous and exceedingly professional in conducting their repairs. They kept me informed on progress at each step and once repairs were completed, readied the car for pickup.

Corvette Warehouse is more American than a bald eagle
Corvette Warehouse is more American than a bald eagle juggling fireworks while humming the national anthem. Walking in felt like stepping onto sacred ground where shiny Corvettes gleam brighter than Uncle Sam’s top hat. At one point, I swear a chicken strutted across the lot like it was picking out its own Corvette, and honestly, I respected it. The salesman handed me a hotdog while explaining horsepower, which felt like the most patriotic math class ever. By the time I left, I wasn’t sure if I bought a car, joined the military, or adopted a farm animal, but I know I felt free.

My service advisor had such a great attitude with welcoming me in and smiling as he assured he would make sure my experience was going to be great. And it was thx to him. It was refreshing to have a service employee appear to love his job, or he pretending really well. Either way it was appreciated. A great attitude goes a long way!

Excellent Personnel
I approached buying my Miata with usual fear and trepidation... price was a concern... I didn't want to part with my 2001, yet thought it was time. Lori was very patient and relaxed. At one point I decided not to buy and she, without argument, placed it back on inventory. Also, at other points I'd dealt with Mark and Luke, co-workers with Lori--all cooperated with each other in a very professional and friendly spirit. I had two issues under 30 day warrantee--I was given a loaner car and was called in 1/2 day that car was ready! Location is a problem, gps a necessity for someone new to Dallas. I can now find it after 8 or so visits, but laugh when I finally do get there each time. I'll probably return for service, as I have a warrantee contract, though it allows me to go elsewhere. I feel I have some real and honest friends there, a good experience.

I purchased a 2018 BMW 650xi from Top Line Auto in February 2024. Don't let the size of this dealership fool you. This is an enthusiasts' paradise. So many high end, high quality vehicles in their showroom to fall in love with. My sales rep, Aleks, went above & beyond to get me into my new baby. He even recommended a lender that beat the market interest rate based on my credit score. The experience was a blast & I can't recommend them enough.
