I think the 10% attrition rate is way low.
Over the years I have seen so many totaled.
The more affordable they become the more they seem to be finding their way to junk yards.
Not only does it take mearly the thought of the hat dropping for an insurance agent to total them it seems more and more find their way into the hands of less qualified car owners rather than enthusiests that were willing to spend higher dollar amounts for performance sports cars.
This is a generalised opinion I know there are owners very qualified so you needn't jump me for this statement.
