I made an air cooled 911 purchase 2 1/2 years ago, since then as to be expected I've concentrated my quest for info towards that type of Porsche and have been nothing short of fascinated and enamored with the cars / information and the group of guys involved. Spend a bit of time browsing Rennlist, totally different vibe than from the 986 Forum.
The cars as others have noted are an entirely different animal from the Boxster, but for me at least I would never consider dumping my 993 911 for another Porsche variant, IT IS that cool. From what you have described (prior owners did the heavy lifting maintenance / rebuild wise) I wouldn't think twice about buying it......
