I can't really say if the Moomba holds its value because I don't know. I have observed that new Moomba's tend to start at a significantly lower price when compared to competitors such as Mastercraft and Malibu. The lower price may not mean cheap (low quality) and could be an indication of high value (you get more for your money) boat. How that translates into resale value is a good question. When it comes to a 10 year old boat, the condition will greatly determine the boats present value.
FYI - I have always liked the Moomba for their high value proposition. It is difficult to find another boat in the same class that gives as much for the price.
I have always been interested in the Moombas---can anyone give a general background on them?
I was told Moombas were a great value because they bought all the old Mastercraft hull molds, and are basically a Mastercraft done on a value budget.
