Nicest truck I’ve ever owned
Got the Duramax Sierra SLT crew cab with pretty much all the options, I’ve tried other trucks and currently have a 2007 Chevy Duramax and it turned me to GM from the ford and dodge diesels I’ve driven/owned in the past. Blows my mind with all the options, super comfortable and rides quite nice for a truck.

Shaun and Brad are great
Great experience with Shaun and Brad, they were very straightforward and made the car buying process simple and fast. Would recommend buying a car here.
Awesome truck! Wouldn't Sell, but Moving
This truck is one of the best vehicles I've owned. It is super reliable and has the strength to haul or pull what I need. Just put a new bed-liner in, which looks great. Also, the music system is great - comes XM capable.

Great buying experience!
Great buying experience! Our salesman Mike Penna was great to work with! Took the time to make sure we found the car that best fit our needs!
Good truck
Good tow truck and good ride for a vehicle. My wife enjoys the extra room in the full size back seat. This is my third GMC vehicle and I am not sure that I wouldn't own any other vehicle.

Great ending to a bad travel experience.
Driving cross country with my son, who was moving to Iowa from Washington state. His 2002 Toyota with 200K + gave up on I90 on the Missouri bridge and he had to be towed to a shop. Willrodt Ford was the only shop in Chamberlin that would make time to look at it. Got there and could plainly see the cracked engine block. Patrick in sales did a great job working with us in my son's budget and set him up in used car that my son now loves. No high pressure sales, no unpleasantness, got back on the road and finished the trip in a lot nicer car than we started in. Only slight delay was they wanted to to a full lube and oil before we drove off. If they weren't so far from Seattle, I'd be looking there for my next car too.

Wonderful, no hassle experience!
Wonderful, no hassle experience! Zora was a delight to work with and made sure we had a seamless experience. He was no pressure and fully informed - also gave us a great price on our trade in. Highly recommend this dealership and Zora. Nice to find someone so reputable, you can't go wrong with ZRV.

I highly recommend Zenith Automotive.
I highly recommend Zenith Automotive. They were not pushy or persuasive and they seem to genuinely care about the cars they sell. They even paid for a battery several months after I bought the car.
