Does an aircrafts' value increase or decrease over time?

if talking new aircraft decrease in value rather rapidly!

however, if @ older aircraft selling more sold new! sounds funny check 1965-1980 aircraft, of them have current market values on cost @ time produced. increase in value, not cost of living has changed on same time frame , expenses related aircraft exceed increase several times.

in 1969 cessna 172 sold 12,500 , "skyhawk" 13,995. today, somewhere in 30,000-40,000 range depending on condition, times, engines , avionics. on 100% increase in value. not, it.

had invested 10,000 in berkshire in 1969 worth 366 million today! (http://www.dailywealth.com/767/the-gift-...
172's value in perspective? add money spent on aircraft during years , negative.

if asking, can buy plane, fly it, sell out without loosing capital? answer yes, if know buying , true market value additions , care , feeding. since no 1 can predict today's economy might 10 years before happens. if buy new aircraft sell less in 10 years paid it! check cirrus sr22 prices 2001 models vs new costs! less 1/3 of list!

don't buy aircraft if reason own see increase in value! happens not routine. owners sell less "invest" if call investment!

right aircraft can return more purchase cost on last few years has not been case @ on aircraft. still have insurance, maintenance, hangar, fuel, , other expenses not returned. if update avionics, see 70% of cost (not including installation) on upgrade though aircraft sell more not return money.

aircraft cost money. of may deductible, may recoverable, , in cases might own 1 few years , come out near don't count on it! can make money buying , selling, yes done or there wouldn't dealers. average pilot owner, isn't case @ @ least not last few years, economy improves may change @ least has in past. easy in 90's , 2000's buy, fly, , sell , come out on deal, not today "deals" available! check housing prices used gain.
