Quinn... I looked at Calabria quite a bit before buying my MB. My buddy has an '06 Pro V that I've spent some time in.
PROS: The best thing about Calabria is super wide beam and cab forward design makes for a huge interior. I also like how affordable they are.
CONS: The freeboard is very low. It's just a super shallow boat. That made me nervous with little kids. Ballast is also small.
As far as price. I would not pay $31,500 for an '05 Pro V. I looked at an '04 Pro V several months agao with similar hours that was priced around $25k. I seriously considered purchasing a brand new, leftover '07 Pro V2 for $32k (loaded with heater, tower speakers, sub, amps, racks, etc.) or had my choice of two leftover '08 Pro V's for $35k. If you are interested in details on these boats, I think they are still available. Send me a PM... you wouldn't have to drive too far.
