Herring Ford review
I purchased a 2011 F-150 back in December no problems with vehicle & the Sales Manager was willing to negotiate seeing I came all the way from Hattiesburg & this was the only place out of many I visited that would even try to work out a deal. Most likely this is where I'm going to buy all my vehicles

Mandal Buick GMC Inc.Reviews
Mandal Buick GMC Inc. review
Visited local dealers that included Ford, Chevy, Nissan and test drove vehicles at each but was surprised by the GMC Canyon. I originally wanted an F150 but price, size and quality issues made me rethink that purchase. I test drove the only available Ranger within 100 miles and did not like it as much as the Canyon. Staff was straight forward. No back and forth. Easiest car buying experience I've ever had.

Great service after the sale. I needed new shocks on my truck. The service time was quick. I have been driving with the new shocks for a week and have no issues.

Legacy GMC review
Update were timely... the tire was replaced in just hours... Thanks Jacob for your help and time. My 2016 Chey Silverado run great on the open highway.
2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

2026 GMC Sierra 1500 review
This is my first GMC and I absolutely love my Sierra 1500 Elevation. The 5.3L v8 is more than enough to pull my camper, I love the stylish interior and it is comfortable to drive. I also felt with the financing and discount specials this was a great deal.
