I have to disagree about the sale price of aircraft that have been repaired by reputable companies, the sale price usually firms up after about a year when the market has forgotten that the aircraft had an accident and has seen it flying for a while.
I tend to agree closer to you A&C, what I have personally witnessed is properly repaired Cirrus aircraft do take a knock of around 10% if you generally compare to the market, certainly not peanuts or 30% cheaper. As time goes on the relevance is still a factor but softens.
Also out of the 39 Cirrus Caps pulls 9 are flying again, so lets call it 25%, they will have been repaired to a very high standard.
You could argue a Cirrus has never yet had to 2 pulls, so the repaired aircraft to date have a 100% safety record
Also the business about avionics suffering from the impact of a Caps pull, I am yet to here any evidence of this being reality.
