If my only choice to purchase a boat would be from Marine Max I would get out of boating, I have yet to meet the average buyer who has had a good experience after the sale.
Most buyers made their purchase because is was a good deal not because they liked the sales rep or felt they would have great service afterwards. Most consumers don't even think about those things until they need it. It's all price price price.
This will change eventually I hope... My $.02
