Depending on condition and hours, that boat should be int he $25-$28K range. As 242's keep dropping to the $30K or less range, the 240 will be less.
I see your profile says you have a 2014 already. I am assuming you put something in there to get past that portion of account setup? If you were in the market for a 190 series, and are now looking at a 240 series, tell us what you plan on towing this boat with. Many folks looking at a 19 footer are only a boating couple, or they have an SUV with a lower towing capacity.
The 240 series are not a small boat, so keep that weight in mind and check your tow capacity. Otherwise, as said above, the tower is an amazing towel rack, but it is great for speakers and grab handles. If you ever get the chance to tow, you will appreciate being able to monitor the rope.
Good luck, and update this thread with your progress.
Boat buying checklist:
Trailer condition: Tires, bearings, lights, service records, Winch and bow stop
Boat engine condition: Oil change interval, hours, spark plug condition, compression test, service bulletins or recall work SEA TRIAL!!!
Engine bay condition: Oil or water in the bilge, cleanliness of the engine bay (it should be clean), blowers functional
Operation during trial: Engines idle, no overheat or other warnings/codes, Engines come up to speed together, no cavitation, Steering is not stiff, throttles move freely, check reverse
Pump inspection: Grate is in tact, impellers show no damage, reverse buckets show no damage, minimal corrosion, condition of sacrifical anodes, clean out plugs
Cosmetic inspection: Seats, carpets/flooring, ladders, safety equipment, lights, switches, bilge pump, horn, gauges, batteries, and the complete hull, watch for spider cracks and gouges into the fiberglass. Most dock rash only into color can be buffed out. Use it as negotiation like it's life or death with the understanding that it will be some quality time with buffing compound and your beer of choice!
