I fully understand your trepidation.
we were lucky, we bought our 2002 S with 27k miles on it. I had read on this forum about the outrageous charge for a glorified oil change Porsche wants for a 30k service, so I made it part of the deal to include the 30k service at our already agreed-to purchase price.
I know owning a Porsche is special and it's a very special car, but come on.
It's time for our first oil change....$200 at the dealer, so I am boning up via this forum on the tools and procedures I need to do it myself.....
It's a Porsche, NOT a Ferrari
