Need help pricing a generator

My friend asked me to help him sell his generator that he no longer needs. I see enclosed ones for sale for $30k but they don't have the automatic transfer switch and batteries and whatnot. But up this one isn't enclosed. I see similar looking ones but they aren't the same model and prices vary from $7000-35000. And I think the auto transfer goes for around $5k.Attachment 60781Attachment 60782Attachment 60782

Attachment 60780

I'm sure he would deliver within reasonable distance so that probably makes it easier for somebody. But I'm just curious if anyone here knows more about these and the market and/or if anyone here would even have an interest in this one.

here is what I know about it:

generac model 440fdr8035gg-f915

ins. Class F

2 CAT 153-5720 maintenance free batteries which are 1500 CCA 12 volts 132lbs each and about $330 new each

automatic transfer switch and I assume for 200KW

Can't help with pricing, but thats one hell of a generator!
