I've been going to Serra in Washington Twp for years and
I've been going to Serra in Washington Twp for years and can honestly say that I've never had a bad experience. They've always been able to get me in on short notice and fix the problem immediately. I go there for everything car related now because I know that I'm in good hands. Wouldn't go anywhere else!
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!

EXCELLENT service.
EXCELLENT service. Showroom and Service Dept staff are always friendly, professional, polite, and very helpful in addressing our questions and concerns. We have dealt with Causley for many years, and their excellent service is what brings us back.
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.
