We have updated reliability stats for the Boxster and Cayman that include owner experiences through June 30, 2010. Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.

Repair frequencies, in terms of repair trips per 100 cars per year:

2008: 36, better than average

2006: 47, better than average

2005: 49, better than average

2004: 67, about average, small sample size

2003: 94, about average, small sample size

2002: 118, about average

2001: 115, about average

2000: 92, better than average

1999: 117, about average

Important note: these cars are only driven an average of 5,500 miles a year, about half as much as the average car. No adjustment has been made for this.

Very consistent results from year to year. The result for the 2000 might be a bit lower than it should be, judging from the results for other model years.

I'd like to report specifically on the IMS failure rate, but we will need more participants to do this. So far, with 180 986s participating for an average of about six months, only four IMS failures have been reported, two of them over a year ago.

Thank you, once again, to everyone who has been helping. We'll have further updates, possibly including additional model years depending on the number of participants, in November and February.
