No, it's not.


In 5 or 10 years, how many people are going to buy
a plane from the 60's to be flown 100 hours or more a year?

As many if not more than today.


The parts issue
starts to get less important to people buying a collectible as opposed to a
working plane. I believe the FAA may have an adverse affect on the older
working planes over the next few years. The cost of operation will be going
up. ( by working plane, I mean one that is bought by someone that places
more value on the flying part, than the owning part).

Baloney. The 50's thru the late 70's planes will always sell well
because that's when most of the planes were made. You will always have
less popular models such as the cheap Beech products but even they will
still sell. Models like the Cessna 140/170/172/180/182/185/205/206/210
can be easily sold today and will continue that way for the indefintite
future. Likewise with the Cherokee line.
