Twins Auto of Dublin review

I was very satisfied with Zaid and the rest of the staff

I was very satisfied with Zaid and the rest of the staff at Twins Auto of Dublin. They have a great selection of used cars that tend be "higher end". Zaid was extremely knowledgeable about every brand and model. He wasn't overly pushy, which I appreciate. They were quick, painless, and fair when it came to negotiation and the financials.

2020 GMC Sierra 1500 SLE review

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!

Mark Wahlberg Chevrolet of Worthington review

Austin Chapman is one of the most wonderful people I have

Austin Chapman is one of the most wonderful people I have ever met. Buying a car from him was a completely pleasant experience. He went above and beyond to make sure that I was happy. My happiness was so important to him that he again went above and beyond. He is a great asset to that dealership. Very impressive young man. Extremely professional, extremely polite, extremely compassionate, and absolutely loves his job and what he does. He made a difference for me and I hope that he makes a difference for many more. Thank you, Austin, you are amazing!

2020 GMC Sierra 1500 SLE review

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.
