Being a brand new cayman owner I started thinking about whether I would buy
another Porsche after this one breaks down or upgrade to the next model line.

Do you think in 5-6 years Porsche will still have cars that are competitive in performance/features/price/etc with so many brands coming out with high performance cars soon? I noticed many people feel they are paying way above a premium for the cars compared to other brands. Personally I love my cayman and if Porsche doesn't offer anything I like that is better or just as good when the time comes I'd have no problem switching brands or keeping the car forever.

BTW, does anyone have a general idea on how long the engines can last in mileage?Thanks.
