I also recall them based at Anderson KAID, communication was quick, their email newsletter is nice to see their newest listings, plenty of information, photos and logbooks usually already scanned in online, prices always seem good and their stock moves. I posted about the Cessna 150 Aerobat on here, asking questions about it as it looked nice, it was listed by Indy Air, and already sold. I was surprised as I thought the price was high and I am not really that good at pricing the market, they must be pricing their airplanes right for their turnover.
My introduction to Indy Air was years ago before I bought my airplane, I flew down there and they arranged someone to flight test the aircraft with me which was nice, I liked it and put a deposit on it, then due to me being new to aviation I didn’t have my ducks lined up, trying to get a prebuy done was becoming a challenge, and then I was also concerned about the wing spar AD, so I mentioned that I wanted the Seller to have this inspection performed and they said ok, and then my mechanic got back to me and had a heart attack about the number of hours on the aircraft. For the price it was ridiculously cheap, and had better avionics than I have now and a working autopilot, maybe would have been a better route or a maintenance hog, who knows. Due to some uncertainty with the wing spar AD and I needed 2 weeks for a prebuy, we agreed to release the aircraft and my deposit was promptly returned.
I have recommended Indy Air to others who have purchased an aircraft from them, and I do receive their newsletter and if the right opportunity presents itself I would buy through them and recommend them. Mostly due to their organization of photos, records and logs, I know their pricing is good, and they are also pretty close to me. If I had any suggestions it would be for them to be more of deal closers and help hold the buyers hand more through the process.
