Boxster Warranty?

If you buy a used boxster is the warrenty still 6 years or 100,000 miles?

Also I am buying a used Boxster. If I get 70000 miles I can get one a lot cheaper. How many miles is to much. With those with experience in owning a boxster for a long time. When did problems start o arise beside the simple stuff like spark plugs etc.
Thanks

Standard warranty is 4yr 50,000. Buy the newest lowest mileage car you can find for your budget. Every car can have it's problems, but I have had none 2 yrs and 13k miles later.
