Rolex ladies platinum president

[tnt]

Have two questions please. Just two, no more no less, I promise

What is the fair or/and good price for Rolex ladies platinum president 179166 with glacier blue diamond dial in K serial? it has 2 years warranty from Rolex service center. All box, tags, papers are included excepted missing 1 link?

And, same condition above but no Rolex service nor warranty with Z serial, and prices $1750 more (counting cash rebate from AMEX). Which would you take?

Both have mint condition.
K takes credit card, while Z does only accepted Wire. They are trust sellers I would say.

After this purchase, I am done with Rolex

Thanks a bunch!
