well, how close to your reserve did you get? I could understand not parting it out if the price got near the reserve, but for a car in that shape (good) with such low mileage, I'd think you'd easily get what you're asking - if not more - parted out. New price on a SC is what? $5k? You'd sell that sucker easy for $3,500-$4,000. $1,500-$2,000 for the wheels & tires, $1,000 for the hardtop... All these things should sell easily here on s2ki. My neighbor recently paid $22k for an 02 w/30k miles (completely stock)... charge a bit more since it's got the stereo system, that more than makes your reserve right there without even considering the I/H/E...
I realize it's a PITA - both in terms of putting to stock and selling multiple parts - but if you're not in a rush, I think you might actually get a good bit more parted out than you're asking as a package.
Not that you haven't thought of all this... but hey
Good luck with the sale
