Vic took his time with us, did not rush, and had an answer for all of the questions we, my dad and I, had. He was patient and understand my needs. He did not try to pressure or convince us into buying anything. But I fell in love with the red Audi A4 2018. I was in and out in no time and the paperwork process was swift and simple. I couldn’t be happier.

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Was looking for a new 2025 Bronco Sport Badlands
Was looking for a new 2025 Bronco Sport Badlands Sasquatch. Found one at Capital City. Mark had it ready for me to see and test drive when I got to the dealership. They were helpful to get me in the vehicle I wanted and helped with financing.
Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

Working with Jerry at J&M Auto Sales has been amazing. This is the 2nd vehicle we have bought from him, and he makes it a seamless experience.
I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

Many thanks to Javy Labrador and the team at Andy Mohr
Many thanks to Javy Labrador and the team at Andy Mohr for getting me into my new (to me) Sierra 1500. This past Saturday, my wife, kids, and I went to a few dealerships before Andy Mohr and we either couldn't find a truck we liked or the numbers just didn't work. Javy took his time and was able to deliver exactly what I needed. He actually took what was turning out to be a stressful day and made it a fun experience. They worked very hard to get me the car that I wanted while staying within my budget. I recommend everyone who is looking to buy a car in Indy to check out this dealership and ask for Javy.
