Hi Lancelot,
Bought a Bav 30 of the same year this April. We're very happy with the accommodation, sailing performance and general standard of kit. Also, as tghe others have said, she's capable of up to 7 knots under engine.
Problems we've found with ours - nothing major, but:
Water pump very noisy - needed servicing;
Deck winches also needed servicing - graunchy to say the least!
Garmin chart plotter - charts no longer supported by Garmin, so no update available. We had to upgrade to a new unit. (We sail off the West coast of Scotland, and the supplied chip was for the Channel!)
Nothing else, so all very minor, really. Ours is also the deep keel model, great when close hauled. Need to be a little careful in shallow waters, of course... The price sounds reasonable - less than I paid fore mine!
BTW, I also have experience of the Cobra - great sea-boat.
Best wishes whatever you decide.
Chris
