Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

⭐️⭐️⭐️⭐️⭐️ I had an amazing experience at Excalibur!
⭐️⭐️⭐️⭐️⭐️ I had an amazing experience at Excalibur! I bought a BMW from them, and not only was the sale price already \$2,000 lower than anywhere else I looked, but they also gave us an additional discount of almost $500 on top of that! Victor was friendly, straightforward, and made the whole process smooth and stress-free. I took three different test drives. Highly recommend checking them out if you're looking for a great deal and top-notch service.

Sports & Imports review
This dealership was to me way down in Pasadena.
This dealership was to me way down in Pasadena. Truthfully thought about turning around on Wednesday. Decided to keep going. Arrived and was met by Robert, a totally up front individual. He pulled out the vehicle gave me keys and said try it out, I will talk to you when you return. The professionalism he possessed was exceptional. We had a 45 minute discussion and I bought the vehicle. I explained that I had no way to get back to the business, from just below Towson to pick up the vehicle. Robert didn't hesitate and said not to worry we will work something out. They delivered my vehicle on Friday and gave me gas $. This was totally the exception and a worthwhile experience.

stopped by Z Auto Sales after seeing a car online, and the experience was honestly better than I expected. The person who helped me wasn’t pushy at all and gave me space to look everything over at my own pace. They were upfront about the details and answered my questions without trying to upsell me. The whole process felt relaxed and straightforward. I left feeling like I actually got honest help, which is rare these days.thanks tony
