Ingersoll Auto of DanburyReviews
Ingersoll Auto of Danbury review
I recently purchased a new Chevy Silverado EV Trail Boss from Ingersoll Auto of Danbury, and the experience was excellent. Spencer Hoch was incredibly helpful throughout the entire process. He made the car-buying experience smooth, straightforward, and completely pressure-free. Spencer took the time to answer all of my questions about the EV and ensured I felt comfortable with my decision every step of the way. I am absolutely thrilled with my new truck and highly recommend asking for Spencer if you want a hassle-free dealership experience!
2015 GMC Sierra 3500 review
This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

Royal Motors Inc. review
I just had the most wonderful experience with Jason, Mike and Kat at Royal Motors in Voorhees! I'm 76 and buying my car through them was a pure pleasure! They all could not have treated me any better if I was family and now I feel like I'm family. I will never go to a large car dealer ever again. I dealt with Jason for a few months. Jason asked me to be patient and now I have my dream car. I told him I was not in a rush for a new car but I wanted to get exactly what I wanted and Royal Motors came through. Don't ever waste your time and money with another dealership ever again!!! Pat Schlussel

2015 GMC Sierra 3500 review
This is a very clean, serviced and useable truck. I "live" in my truck and needed reliability, but without the garish price of new. All my tools fit and it is very handsome interior and exterior.

Keast Auto Center review
Great to work with. I love my car. The process was smooth. This was an out of state buy and, when buying out of state (I have bought out of state quite a bit) you have to make sure the seller tells you everything, pictures, videos, everything. This dealership was so accommodating. Answered all my questions, took pictures for me. Would buy from again. Very honest.
