Freightliner value

I have a 2015 Freightliner Casacadia that was a good riding/pulling truck that now has a gremlin somewhere in the wiring, my mechanic can’t seem to pin it down and the truck has just been sitting. Just wondering if any of you had a good guesstimate of its value as is.

Good running motor with its share of miles, transmission is a good shifting one. Just frustrated with it sitting
