We've updated our reliability stats for the Boxster to include owner experiences through March 31, 2013.
Repair frequencies, in terms of repair trips per 100 cars per year:
2008 Boxster: 38, low
2007 Boxster: 43, low
2006 Boxster: 21, low
2005 Boxster: 21, low
2004 Boxster: 52, low, small sample size
2003 Boxster: 48, low
2002 Boxster: 64, low
2001 Boxster: 46, low
2000 Boxster: 23, low
1999 Boxster: 105, moderate
We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:
2008 Boxster: 69, < 1
2006 Boxster: 83, < 1
2005 Boxster: 85, < 1
2001 Boxster: 60, < 1
Still no reports of IMS failures since the beginning of 2011.
We'll have further updates in August and in November. The more owners participate, the more comprehensive and precise these will be.
