I had a great experience at Fishers Imports when purchasing my Audi. Sam was very helpful in the process of finding a car to fit my needs and made my experience pleasant.

I recently purchased a new GMC terrain from Andy Moore Buick in fishers Indiana my salesman James Bogan and Ahmed Nasfi Were absolutely the best I am an older lady and I have purchased several vehicle in my life and I think dealing with Andy Moore and these two gentlemen was probably the best experience I’ve ever had purchasing a vehicle so my hat is off to both of them and I would highly recommend either one of these two. They were both great and by the way, I love my new car.

Excellent Company!
I was in the market for a used SUV and found a Hyundai Tucson at their location. I test drove it and bought it the next day! The car was in great condition and had low mileage. Super easy process, helpful staff especially Mitchell. He’s excellent at his job and doesn’t cut corners and keeps it honest. Unlike most car dealerships, they’re pushy and “up sell” cars but at Indy Luxury Motorsports, they let you make your own decision and your own pace. Definitely give this place a try!

Proactive Service
It started when Matt saw me drive in to the service bay and walked over to greet me with a smile. I had a question about our navigation screen that honestly was driving me nuts—he showed me how to fix it in a jiffy. We were in for a simple oil change, but Matt also after checking our tires warned us that new tires would be coming due and provided a few estimates so we could prepare for that upcoming expense. We always feel special at Skillman because of members like Matt.
