In February 2007 I bought a Porsche 911 Carrera S Cabriolet. This page details the events and highlights of my ownership of the car including maintenance and repair issues.
One of the lessons I've learned during my life is that it's often difficult to tell ahead of time which issues and events in your life will grow into major ordeals. Accordingly, I think it's wise to pay attention to the details for everything since you just never know when the details might become important in the future. It is with this archival spirit that the page you are reading was created.
If you are considering purchasing a Porsche of your own then I hope that the information available here is useful to your decision making. While the plural of "anecdote" is not "data", it's often nice to be able to see what another person's experiences have been.
Why a 911 and not a Boxster? It was a tough call and I don't think there is a single right answer. I posted to Rennteam.com some of my thoughts on the matter.
I no longer own this car. I sold it on 31-Aug-2009. See my other cars for more information.
MSRP was $102,040 and I traded it in for $47,000.
Maintenance cost an average of $325 per month in hard costs.
Depreciation added $1,835 in soft cost each month for a total ownership expense of $2,159 a month.
The car depreciated 53% during the 30 months I owned it. It was a trade-in sale, so presumbly depreciation would have been less grim with a private party sale (but not by much).
Fuel and insurance is not included in these figures.
Maintenance cost per mile: $0.26
Repair cost per mile: $0.08
Depreciation cost per mile: $1.50
Total ownership cost per mile: $1.84
I put 35,431 miles on the car while I owned it (1,181/month average) .
Maintenance cost an average of $243.28 per month
Repairs cost an average of $99.10 per month ($0.08/mile).
