Eric and staff were able to fit my truck in for warranty
Eric and staff were able to fit my truck in for warranty work faster than expected. He worked with the warranty company and assisted in smoothing out a few bumps in the road. All staff was friendly and helpful during the process. I would recommend them to anyone needing vehicle work or an upgrade to a new truck
Nice for what it is
Meets my needs. Plenty of power. Lots of room. Hauls and tows like a dream. Very nice and stylish truck considering that it is a W/T.

Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

Great customer service
Very helpful staff. Absolutely no pressure to buy from Corey during the early phases of my shopping . Visited multiple dealers trying to find the right vehicle. When made decision on vehicle Corey and Steff did all the work. Online questions answered almost immediately. Even stayed late to accommodate my schedule. No hassle buying process. Made the 50 mile trip well worth it. Will definitely look here when in the market again.

Very happy customer - I highly recommend Snell
I would highly recommend Snell's auto due to great customer service - including professional, friendly, knowledgeable, and very helpful staff. Specifically, Emily Brennan and Jackie Taylor who both listened to my needs, and helped steer me away from making the wrong choice (I was looking for a "beater" truck and was prepared to spend up to about $10,000 - and I had found one online which was there when I got there, but upon seeing it, I quickly realized it was not in good condition and it wasn't the truck for me). Emily helped me talk through xxxxxxand con's of moving into a higher price range (up to $21k) and she recommended the truck that I ultimately bought (a 2012 Ram in great condition with 125k miles) and I couldn't be happier. It's everything I wanted and more, and I feel like it was a fantastic bargain. I felt valued as a customer, and I've never had a better vehicle shopping experience. They even did the license plate, title, tags, etc. all right there - I didn't even have to go to a notary. Thank you Snell - keep up the great work!

I bought a 2021 Chevy Trailblazer from Runde Chevrolet.
I bought a 2021 Chevy Trailblazer from Runde Chevrolet. The experience was the most fun I've ever had finding a vehicle. The team took very good care of me. I wouldn't hesitate to use Geoff Barklow again. I will return. The truck looks great and as a Healthcare traveler, I don't have many worries about being stuck in the cold states as winter approaches. I feel confident that this truck will take good care of me as well.

I went to look at an '06 Miata I'd seen on line. They had 2. They worked with me on getting the one I wanted with the wheels off the other one. Excellent! They helped me with financing. I drove away with a car I've always wanted. Randy was very helpful and never pushy at all. Very friendly and professional. I would definitely recommend Parkway Auto
