Found on Denver craigslist, '01 Boxster S with 3.6 conversion
 

I drove this '01 Boxster S a few months ago and would have bought it had I not found my '03 S for a screaming deal. It was built and is owned by the owner of a local independent Porsche/German car specialist shop. The ad doesn't have much info, but from what I was told when I went to look at it is has all the engine update goodies along with the 3.6 conversion. I do know that it is definitely fast and handles incredibly. No affiliation.
