As an owner of a well sorted 1973.5T 911 that I have owned for over twenty years now, I can say the following:
I agree with most that the value of these cars makes them less likely to be daily drivers, are driven on pleasant days void of rain, snow and sleet, spend most of their time in garages or under cover and usually show up only at car shows, club events and if your daring enough that club ride through the mountains to visit a winery.
They all seem to hide until the first sunday of each month when 600-800 vintage/collectibles show up at the Caffeine and Octane event at Perimeter Mall in Atlanta, Ga.
Here in Atlanta I rarely see any older or vintage sports car driving around even on the weekends like I used to. The Porsche market in Atlanta is the second largest in the country too. For myself, the cost of repairs and parts, which have skyrocketed keeps me more conscious of my driving. A bad shift can be very costly! Besides this, the number of mechanics who are talented with the older air cooled models are retiring and just a few are around.
So what do you do? Well for me, I turn 72 soon and have been a Porsche owner for the last 45 years. When I walk into the garage each day and see ole Misses Brown in all her glory, I see art, automotive history and an elevated ego. Sure she's worth some serious cash, but for now I think I will just continue to enjoy this grand old car.
