As a professional salesman (not the sleazy kind
) I've learned over the years that a thing's value is exactly whatever someone is willing to pay for it.
If it isn't selling in your desired time-frame, then one thing is true; You haven't yet found a buyer who thinks it's worth the ask. So one of two things must happen (or both): You adjust the ask to what the current pool of buyers is willing to pay, OR - you increase the size of the pool of buyers. That means more assertive advertising, get it in front of more people, more often.
For instance: I'm a frequenter of several Boxster FB groups, and I haven't seen this listed on any of those (I know that can be a pain). I haven't seen it in my Craigslist searches. I haven't seen it on Ebay. etc etc etc
FWIW: For me, if it were a '99 or older, I'd be all over it, as I suspect many others might be as well. But an '01 roller has zero value to me. Even at $2k, it's about $1900+shipping too much for me.
Just some food for thought.
