Thinking Of Buying a 1982 V-20 Fisherman

Seem like nice boats. Never had a Wellcraft before but have heard good things about the V20 hull. The boat is in pretty good shape. Transom work recently done, hull and floor reported to be solid. Some electronics - but nothing extravagent. Has a 150HP Johnson on it now that runs good but has some hours on it. Any advice? Things to look for? Questions to ask?

I want to fish Lakes Erie and Ontario. Seems like this platform (8" beam I think - right?) ought to be pleanty stable even in some chop?

Any advice appreciated. Asking price is about $4500 or so.
