C-182, P model carries a good load, 4 real pax, full fuel. Simple systems, NO fuel pumps, fixed gear, reansonable speed( 144 kt) 13 gph , reduce the power to 60%,120kts,10 gph. Same speed and fuel as a 172, but can carry a load of almost 1200 lbs. A 172 will NEVER do that for the same fuel burn. Insurance is a plus also, check it out. Also the market is for resale, if need be is good. Anyone who has flown a 182 will agree it is a good investment. Note, prior to 1976 it should be STC auto fuel complient, should avgas get unreasonable.
