2012 GMC Sierra 2500 SLE review

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.

2012 GMC Sierra 2500 SLE review

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.

2012 GMC Sierra 2500 Work Truck review

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.

Willrodt Ford, Inc. review

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.
