Interesting report I just read I know it's Canadian but nevertheless....
Consumer Reports Best and Worst reliabilities in cars

Second last para on the bottom of page kinda surprised me, should have picked up my son's Boxster last year when I had the chance:
"While European reliability had been improving, momentum seems to have stalled. All Porsche and Volvo models are rated average or better. But Audi, BMW, and Mercedes-Benz are among the worst automakers overall.

The Porsche Boxster has the best predicted reliability in our survey, while the Audi A6 3.0T and Jaguar XF have the worst."
