After fixing the radio in the Corvette, it was time to tackle the clock. We tried mightily to revive the patient, but in the end, a heart transplant was necessary.
The clocks in the "midyear" Corvettes (1963-67) are electro-mechanical units made by Borg Instruments. They were used in a bunch of other GM cars of the period, in addition to the Corvette. This article gives a nice description of the clock and what commonly goes wrong with it.
These are analog, spring-wound clocks with an electric winder that is supposed to reset the spring mechanism every 3 minutes or so. To see how it's supposed to work, check out this video (currently at 460 views, many of which are from me!). The design doesn't exactly inspire confidence, as it depends on a set of 12 volt contact points reliably closing every 3 minutes or so, pretty much forever. Those contact points build up corrosion over time, which will kill the rewinding mechanism.
The Porsche has been sold and sent off to the East Coast by transport. Time to tally up the total cost of ownership for this, my first "one year, interesting car, fully depreciated" experiment.
So, before we get to the raw numbers, some context. As with any Porsche, maintenance is a big expense on these cars. Even routine things cost more than they would for a typical car (e.g., oil change = $250).
And there were two big, unanticipated expenses. First, the failure of a coolant pipe necessitated an expensive "engine out" repair, which also led to a bunch of "while you're in there" maintenance and upgrades. For the 996tt, the coolant pipes are a known weakness, and thus a risk you take, until it happens and someone fixes it. Chances of it happening are slim in any particular year, and once it's fixed, it's fixed forever. So it's unfortunate that it happened on my watch, but them's the breaks. The next owner doesn't have to worry abo…
There is such a thing as too much car. That's what I learned from my year with a 2002 Porsche 911 Turbo.
Don't get me wrong, it's a remarkable car. The common wisdom is that the 911 Turbo is the "everyday supercar," combining insane performance while also being practical enough to drive every day. That's mostly true, but...
The single best thing I did was drive the car home from Dallas after buying it. On smooth, empty highways crossing the high, dry desert, the Porsche was a dream. I set the cruise control at 125 mph, and the car was happy to go like that for hours. It's utterly at ease at those speeds, with plenty of acceleration still on tap.
In fact, let's pause for a moment on the subject of acceleration. It's really rather shocking ("face-melting" in Jennifer's words). Other than the Tesla Model S, it's hard to get the same feeling of rocket launch acceleration without unnecessary drama. I will miss that.
