The mechanics did a terrific job with fixing the issues
The mechanics did a terrific job with fixing the issues of a major oil leak and radiator replacement. Office receptionist Amanda is always so pleasant and friendly. Jason Guerra is absolutely a wonderful Service Agent, seeing to my need of temporary vehicle access, and he keeps me informed about the progress of the repairs on my 2005 Impala.
This truck has a jerk when changing gears sometimes.

Great dealer
Bought a vehicle from them out of state and they are very up front about pricing with no hidden fees, just a $200 doc fee and state taxes. Felt very comfortable to work with them and was great experience.

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.
