marathon boat info

[rocky]

I was thinking of buying a different boat and i found a 1987 marathon 22 foot with a 165 mercruiser . I really want to upgrade but don't have lots of extra cash laying around with the current economic conditions. This boat is for sale for 4500$ and looks to be in good shape and also comes with 4 downriggers. So i was wondering if anyone has any knowledge of marathon boats and if this is a decent boat before i make an offer? I appreciate any opinions on this boat. Thanks.
