When is major maintenance due ?

[Kyle32]

Hi,

I'm unfamiliar with Porsche's maintenance schedule.
Is there a millage or after X years when major maintenance needs to be done?
I'm shopping for a Boxster and would want to avoid buying one that is just about due for a major rehaul (or least be knowledgeable about it, so I can negotiate the price down).

On my Honda for example, you want to avoid anything around 90,000 miles. So, either get one way below 90k or starting at 120k miles. The reason is that at 95k there is a major tune up, which requires timing belt change, water pump etc.

So, what are those mileages or X years for a Boxster?

Thank You
