Ordered it and it was delivered within a few days.
Ordered it and it was delivered within a few days. Easy to deal with over the phone and not needing to drive to the dealership to get the truck I wanted.
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!

I was in need of routine maintenance including new tires
I was in need of routine maintenance including new tires in between business trips. The service staff was able to arrange a plan suitable for both their and my needs which resulted with successful completion of the work required. Excellent work by the Kevin Meservy and the Team at Jim Causley Buick GMC!
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.

Kelsey was at lunch when I've arrived but was smiles and asked about my service(s) my car was due for. Just an Oil change was needed, she did an overall maintenance check up on the computer since my last visit. Told me about the conditions of Wiper blades & tires, since we are going into early fall season. I appreciated that. Teresa had the day off, Kelsey stepped up and filled some big shoes, Thank you Kelsey for listening to me and telling me what's due in the coming maintenance mile marker chart. I'm very happy customer doing business with Serra Kia as of 9/02/2025
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.

Ask For Rachel Kupke!
I've gotta say, my car buying experience at Serra Ford for the Ford Ranger was freakin' amazing! The whole team there was top-notch, especially Rachel Kupke, my salesperson. She was on the ball, super attentive, and knew everything about the Ranger and Ford's other offerings. Rachel made sure I got exactly what I wanted and answered all my questions like a pro. Candy Serra, the sales manager, was also awesome. She personally made sure I was happy and really helped with the financing process. Candy really cared about making my experience top-notch. The rest of the Serra Ford crew was fantastic too. They were all friendly, knowledgeable, and made the whole process a breeze. I walked in and felt right at home. And let me tell ya, the Ford Ranger itself is one badass truck. The Serra Ford team knew their stuff and helped me find just the right one. They explained all the different options, safety features, and cool tech stuff. All in all, I can't recommend Serra Ford enough. If you're lookin' for a new Ford Ranger or any other vehicle, go check 'em out. You won't be disappointed. They'll hook you up with a great car buying experience and leave you with a huge grin on your face and an awesome new ride in your driveway!
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.

Recall Service Review
My recall service appointment on 9/7/23 was reschedule by Jason Jackson. The reason was the tech going to be out for my original appointment which was 9/8/23. Jason Jackson service consultant at Suburban took care of me very well, I also ask him can we do the works package for an oil change with tire rotation. He said sure we can fit that in with your recall. Jason customer service is always on point and over the top.
