$3500 isn't too bad. Is that parts and labor or replacing the above listed items? If the car otherwise perfect and and $3500 would be how much more it would cost to for that 100% perfect spec, then go for it.

And I can tell the car isn't full leather by the look of the upper door cards.

Another option is to wait for used parts to become available or do a swap (I once traded my beige M3 interior for a black M3 interior).

One issue is how is the arm rest in the door affixed?

Is that parts and labor or replacing the above listed items? Yes.

I can't imagine finding another base black over something else PDK Boxster would be that difficult if you expand your search radius. What is it about this particular one that is appealing to you to justify doing an interior swap? There are currently over 30 certified pre-owned examples of base PDK Boxsters in the nation at Porsche dealers. Here are just three that are within your price bracket that are less expensive and/or have fewer miles but certified.

Buying a car from another state, especially a certified one, isn't really that big of a deal.
