Adam sums it up, but to add details several have had to be replaced the hull falures have been that bad.
We were going to buy one but after hearing several bad reports (also engine quality issues on the deisel version) we looked again at the market, Avor, Benatau, Rodman, and Jeanneau. We ended up buying a Jeanneau 625 which has a far higher quality for a slightly larger boat, as you will see for yourself if you go and look.
Pricewise I will not discuss figures but suffice it to say the deal we got was very competative compared to the Quicksilver and for a far far better boat.
I would also point out that this is a totally unbiased opinion bearing in mind that the Poole Jeanneau dealer is a club member. We did try to source a boat at a better deal else where but we were totally satisfied by buying localy.
