Depends on the buyer, collectors MAY pay a lot to get a box of 2/3rds of a DMU and a spare motor brake .
Modellers like Clive and I would be looking at it to fix the final 1/3rd or just make something different, so go for anything.
I have converted a white stripe PTE and a NSE trailer into a different trailer.
My personal Lima limit is up to £10 per trailer, £20 per motor. So you may get £50 from a modeller.
