You didn't mention what type of sailing you are planning on doing with your new boat.
I own a 1983 P303. (My Avatar). They are exceptionally roomy thirty footers of reasonable build quality. They won't win you many races, but they'll get you to the next cove quick enough. The 2GM powers her quite adequately for everyday purposes, but could be inadequate if you were counting on those ponies in an emergency. The boat is very stiff undersail but will require reefing in fresh winds to reduce weather helm. A shoal draft (4'4"), encapsulated ballast and skeg hung rudder were all pluses for me.
Keep an eye out for blistering and leaking toerails. The tangs attaching the main bulkhead to the cabintop are known leakers as well and should be rebedded often.
If you're a weekend sailor looking to overnight and sometimes venture a little further along the coast, this a lot of boat for the price.
