Without going too much into the issue of value, this seems generally a good "starter" plane for a new owner. The only real concern I have are that it isn't clear how old the engine is, or how long since that major overhaul, no less the top overhaul. The price seems a tad on the low side if it's got a good engine, so I'd look hard at that, because overhauling a 6-cylinder Continental costs a couple-three thousand more than a Lycoming of the same power (i.e., Cont O-300 vs Lyc O-320).
This is certainly an easy plane to own and maintain, which is why I say it's a good choice as a first plane if it suits your needs. Note that it isn't a true 4-seater -- more of a 3-adult or 2+2 with kids in the back. Also, it's not a standard 6-pack panel, and the radios are a bit dated, but still perfectly fine for instrument training and routine IFR flying once you get that rating.
To learn more about what it would cost to own and operate a plane like this (beyond the initial purchase price), email* me for a copy of a paper I wrote on the subject. For more on shared ownership, see the AOPA's excellent guide on that at
http://www.aopa.org/members/files/guides/multiple.html. And an LLC is an excellent structure for a 4-6 owner deal like that -- contact an aviation attorney in your state to talk about the details of setting one up. The chanpters on liability, forming and operating a business, insurance, and buying/selling aircraft in J. Scott Hamilton's book "Practical Aviation Law (4th ed.)" would also make excellent reading -- about $40 delivered from a range of internet booksellers, and well worth it.
