They seem to sell pretty quickly on here when they are $2k... and sit around for ever when they are $3K. But to the right person with the right money on the right day it might be worth $5k.
I bought a KE10 2 years ago that was in reasonably good original nick. I paid $3K for it. Spent probably another $2k on nice bits - venetians, lambs wool seat covers, 4k engine, door rubbers, better lights, etc etc... and ended up not being able to get any more than $2k for it.
So based on that I would aim for $2K :y:
