All of the inboard dealers are on Holiday Rd, left off exit 8 985n within three miles of each other. I don't have any affiliation with any of them. That being said, I highly recommend Atlanta Marine. I bought a boat from them and always had great service through a three year bumper to bumper warantee period and until I sold the boat. I bought it 10 yrs ago and they still treat me like a new customer. They were on top of all warantee issues and Kurt (owner) without hesitation offered to replace my defective skins when the factory (toyota) wouldn't. It is a family owned business and they will take care of you.
They are the top Supra dealer in the nation, there's no other local inboard dealer that can say that about their brand. They were a tiny dealer in '00 when I bought my boat, and they have grown exponentially because they can take care of the customer. They have a great selection of boats in inventory right now.
Atlanta Inboard is the Malibu dealer, they have done equally well over the last 10 yrs, I have no experience with their service dept but I hear good things from other people. Last yr they had about 60 Malibus on their lot, it was scary how much inventory they had, now its down to 10 or so.
The MC dealer has been in the inboard business here a long time and has a good reputation. He changed from CC to MC about three years ago. He has almost nothing on his lot the last time I drove by (last wk)
The Centurion dealer (JOA Marine) used to be the MC dealer and lost them because they were sketchy. They may be OK now but I would not recommend that dealer.
There is a Ski Supreme dealer next to the Centurion dealer, they were selling center console fishing boats until about two years ago. I haven't seen a Ski Supreme on the lake, just in their lot and they only have one or two.
You should take a ride up there and test drive some boats, they're all 5 min from a ramp and will demo a boat in a heartbeat.
