Value of widebody s4 in todays market?

[Tfreestyle]

I know pics and full mod list make a big difference in gauging value but im just looking for like ballpark for a clean S4 avant with oem rs4 widebody(bodywork was done right, great gaps and paint). I havent checked out the car yet but was referred by a friend of the possible sale of the car. Car has a higher mileage chassis, 140k+, with stockish interior but will have a low mileage replacement engine(about 60k) with new k04s, timing belt job, new clutch. I havent gotten the full details of what other goodies are on it and I know that effects the value but has the normal stage 3 goodies. I havent been in the scene or on the forums that much in the past few years(previously had a stage 3 s4 sedan). All the older ads ive been able to find were asking for 25k-30k. Any ballpark numbers with educated guesses? I know i need more info but its what I have right now

Depending on history (number of owners and and accidents), interior quality, aftermarket parts list, and quality of the installation of said parts, I would venture a guess of $20-35K. Then again....we've seen shit box widebody's sell for 12-15K.
