One item I have a question about is TTAF....it seems to me the average TTAF of the 150s for sale I have seen is 4500hr. If a 150 has 9000 vs 3000 would not the moving parts on the airframe basically have 3 times the wear?
I find the number of hours on the airframe is not nearly as important as Vref valuation would have you believe. There are a lot of 150s with well over 10,000 TTAF that are flying around just fine.
I've found that the hours on the airframe detracts from the price far in excess of any actual wear and tear. As with anything else, the level of maintenance received is far more important than the number of hours flown.
PS - as an aside - my current mount has over 10,000 hours on its airframe. I was a bit concerned until A) I inspected it myself, and B) I found out Cardinals used in pipeline control have over 40,000 hours, yet are still flying.
