Warranty Direct have just published a league table based on 450,000 insured vehicles in the US and UK. Porsche came 16th (2 below Ford!). What was striking was the number of engine based claims - 21 each year for every 100 Porsche policies sold. That's four times the claim rate for Jaguar. They don't specify what counts as an "engine based" claim.
Moral of the story? Keep your car under warranty when the original expires. I have had my new engine (at 7500 miles) so am hoping I've had my fair share of trouble!

PS I should add they also don't specify how many Porsches they covered - so the data need to be interpreted with some caution as the sample group could be small.

 

Is there a link we can see this list? I am curious about how companies line up in that list.

 

I read it in Autocar but here is a link to the Boxster reliability index for UK cars only - gives you a good idea. I don't think Warranty Direct cover 911's anymore.
