Dvonte Muhammad reach out to me & his manager helped me
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.

My wife and I came in to essentially browse and compare
My wife and I came in to essentially browse and compare vehicles on Saturday 08/16. We ended up speaking with John Cummings, who was extremely friendly, concise, to the point, and not pushy at all. He also was very honest and transparent during the entire ordeal. Having worked in a car dealer as a master tech for a good portion of my career, I typically am pretty good at picking up on red flags from shoddy salesmen, and I did not get any indication what so ever that John had any of those qualities. We test drove a Hyundai Palisade, which we really liked. I was up front with John on my financing expectations, and also requested that we get the vehicle on a lift for a visual inspection. There was a slight miscommunication between John and management, and they were not able to accommodate my request. What they did offer is the fact that Hiley, and themselves fully believed in their products they were selling, and that they knew for a fact there was nothing majorly wrong with the vehicle. Both Rusty the used car director, and the finance manager Lori gave me verbal confirmation that we could back out of the deal, post down payment, if I got it to my shop on Monday and found something catastrophic. I'm happy to report the vehicle was exactly as they advertised and promised. Next we dealt with Lori, the finance manager for all of the closing paperwork. She was very friendly and a straight shooter as well. She also was not overly pushy with any of the extended warranty plans or any other areas for upselling, as per usual in the finance department. Overall, we had a VERY pleasant experience between dealing with John and Lori. We did have one minor hiccup, which as of 08/18 I am waiting to see if John can possibly do anything for us, the spare key fob does not work with the vehicle, even though it has a new battery. I will revise this review once that issue is fully addressed and/or resolved. If you're looking for an honest salesman that won't lie to make a buck, or push a bunch of up selling onto you, ask for John Cummings.
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.

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.
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!

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 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.

Spencer made this a pleasant experience!
We purchased our Lexus NX from Sewell Lexus and had a wonderful experience working with Spencer. He is very kind, knowledgable, personable, but the most important trait is that he actually listened to what we wanted and worked hard to find us just that. He really came through for us all while making us feel comfortable, valued, and made this process such a breeze. We have never had such a quick, efficient, and PLEASANT car buying experience. Yes, I just referred to the car buying process as PLEASANT! If you are looking to purchase a Lexus, I highly recommend working with Spencer. He goes above and beyond!

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.

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.

Easy process
Worked with Alonso C. in the used car area. Had previously researched the vehicle I wanted (2018 Chrysler Pacifica) and he made the process easy, non-confrontational, and easy. The title guy and I didn't get off on the right foot, but that's probably I intentionally put in a pause to the buying process and had to leave to get my financing from my credit union. Overall I would buy again from this dealership, and Alonso specifically.

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.

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.
