Porsche 911 Turbo: 14 Month Cost of Ownership

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 about it. You pays your money, you takes your chances.

The second big expense was the repaint after a certain someone scraped the rear quarter panel on the side of the garage. Oops. Could have happened to any car, with roughly similar repair costs.

So, here's the cost of ownership break down:
  • Purchase price + tax and registrations: $38,000 + $3,848
  • Oil change, brake fluid flush: $443
  • Headlight washer nozzle: $65 (replaced that one myself)
  • Coolant pipe repair, towing, plus maintenance and upgrades: $8,578 (coolant pipe repair was $3,400 of that)
  • Window regulator: $468 (could have done this myself, which would have saved $250)
  • Repaint rear quarter panel: $2,825
  • Replace torn CV boot: $494
  • Detailing: $600 (you don't just "wash" a black 996tt) 
  • Smog certificates: $114
  • Sale price: $45,000
Net 14 month cost of ownership: $ 10,435.

That is a lot of money by any measure. But almost all of that was the result of the coolant pipe failure (just bad luck) and the garage scrape (not the car's fault). But for for those two bits of bad luck, the total cost would have been a lot lower (although a significant portion of the sale price was the result of the coolant pipe fix and attendant maintenance and upgrades, so resale price would also have been lower).

But let's consider my benchmark for this experiment: what if I had bought a 2015 Honda Odyssey minivan? That's a popular car choice for lots of families out there. A new, reasonably well-optioned Odyssey EX-L would have come in at about the same price as my Porsche. Sales tax would have been the same, registration fees somewhat higher, maintenance significantly lower. Resale value today is $32k, so first year depreciation would have been about $6,000.

So, net cost of ownership for the new Odyssey works out to be roughly the same as the Porsche (sales tax + registration + depreciation). Of course, the depreciation on the Odyssey will slow down, and you only pay sales tax on it one time, so for this coming year, the Corvette won't have as much room for losses, if I'm to stay roughly par with my 2015 Odyssey EX-L benchmark.

Needless to say, I'm very pleased to have driven a Porsche 911 Turbo, rather than a Honda Odyssey, for these past 14 months. :-)

    The 996TT becomes a real bargain when you wrench yourself. Through my first 9 months of ownership, I've had to replace a radiator, two front outer CV boots (first was torn, other I did since it wasn't far behind the first), failed fruck latch actuator, and completeled an oil change. My total bill for all of that was well under $1000. If I have a coolant pipe failure, I'll pull the engine myself and pin the lines. Paying Porsche shop prices on these cars is a real killer.

Fixing the clock in a C2 Corvette

Image
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. Thanks to a bunch of threads on the...

Five Year Miataversary

Image
  Five years, fifteen thousand miles. Time flies.  The car remains a joy to drive. As I anticipated when I bought it , I don't miss the extra horsepower you get in the 2019 and onward model years (aka ND2). That extra power is reportedly mostly at the top of the rev band, an area where I don't spend much time. The joy in this car, for me, is less about going fast than about the ways it engages you in the act of driving.  Cost of ownership? Here's the math:  Maintenance = $1,057 (basically oil changes, plus an engine air filter and transmission oil change) Depreciation = $500 (yes, Kelly Blue Book says I can basically get what I paid for it!) This makes the Miata by far the cheapest car to own that I've had, beating out my 2010 Honda Fit . Most of this is down the the crazy high post-pandemic used car prices holding depreciation in check. But that doesn't diminish the joys of simple reliability, which not all newer cars can provide.  Here's to the next 5 years!...

S550: 12 Month Cost of Ownership

Image
Everyone knows that a Mercedes S Class is an expensive car to own. That's partly why they depreciate so quickly. Well, this car more than lived up to that reputation, proving to be far and away the most expensive car to own of those I've discussed on this blog (compare 2018 Mazda Miata , 2010 Honda Fit , 2002 Porsche 911 Turbo , 1965 Chevy Corvette ).  Deep breath. Total one-year cost of ownership = $27,853. Holy smokes. $2,321/month. I could have (maybe should have) leased a new one for that (although the shortest leases are 24 months, so I'd have ended up spending a lot more total).  The inflated pandemic used car market certainly accounts for a bunch of this. Yes, I knew it was a bad time to buy, and yes I overpaid to get the car I wanted , but I didn't count on another $10k of depreciation in one year. The problem with selling an S550 is the plethora of cheap, minimally optioned cars out there. If you want to get above those prices, you need to find someone who valu...
