Between '00 and '04 , the Boxsters especially the S model had an unusual increase in midshaft failures, necesitating engine replacements. I know I had one. Maybe that is what is showing up in their statistics. Otherwise . I think the Boxster should have the same reliability as the Cayman, barring the complexities of the mechanical convertible top.The latest Auto issue of Consumer Reports lists the Cayman and 911 as very reliable (their highest rating), while the Boxster is moderately unreliable (their 2nd lowest rating). That's unusual as they are from the same platform.
