We have updated reliability stats for the Boxster and Cayman that include owner experiences through December 31, 2009. In terms of repair trips per 100 cars per year:
2008: 67, small sample size
2005: 103
2003: 125, small sample size
2002: 167, small sample size
2001: 125
2000: 129
1999: 133
With more data this time around, we're seeing more consistent results from year to year. Only the 2002 doesn't fit with the others.
The 2002 and 2003, both with small sample sizes, are worse than average. The other years, including those with decent sample sizes, are about average.
I'd like to report specifically on the IMS failure rate, but we will need more participants to do this. A small number of IMS failures have been reported.
A big 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 May and August.
