Aircraft depreciate differently but when they get to about 10yrs old then you really see where your money has gone. If you look at the difference between a Cessna 210 and a Beech Bonanza you will see where the extra money went intially. It's the same with a Cirrus. Because the entire airframe is limited to 12k hours, as much as they try and make this sound like a huge amount on the webpage (cirrusdesign.com) but to be honest 2nd hand buyers will really look into this. It's really the same as buying a 2nd hand turbine aircraft. You need to pass the parcel before you end up having to overhaul or whatever!
