2007 X5 4.8 113k for sale, timing chain jumped, thoughts please.

I am seeking thoughts and information. 2007 X5 4.8 113k for sale, timing chain jumped. Owner was asking $8k, now down to maybe 6k and I was thinking of offering $4k. Vehicle is in great shape with most if not all options.
Owner said wife was driving and it just stopped. Open the oil filler and you can see the chain is off the cam sprocket. My concerns are, is this engine repairable? Hopefully it is just the one bank and would need the head pulled and rebuilt at minimum. Most of the labor I can do however have never pulled a head on an N62n engine or any other BMW engine. ( done lots of Older GM's) I have done a lot of engine work on my 2005 545, Intake, coolant pipe, water pump, secondary air passages, seals etc, but not the timing or head stuff. (She needs valve seals now.. at 182k)
Car would be for my wife who isn't one to pay attention to lights or warnings so my other thoughts are to look for a 3.0 or 3.5 which seems to be less of a maintenance requiring engine.
Thanks for your comments.

Why not buy a used engine, do all the maintenance until engine is on the pallet and be done with it for a few years? I'd do that if i were you. There may be other damage and generally you dont want to put back together engine that may be full of metal and plastic shavings.

My 2 cents...I would offer $4k cash and worst case, put in a used engine...I know that Bavarian Engine Exchange offers used BMW motors...how mechanically inclined are you?

Swap an LS1 in it, call it done (im sure major work)

Thanks for the replies.
Ozer - I would ertainly do an LS1 if I could find out how. Last I tried checking into this on an E53 I could find out what needs to be done so, I think I figured it was just wiser and simpler to stick with the N62.
Pierce330 - Looking at Bavarian Engine Exchange, they don't handle the N62 engine, only older ones otherwise yes I would go that route.
If I could find a source for a rebuilt that would be the way to go, if it wasn't cost prohibitive.
Thanks again for the replies.

N62 are out there.

Here is one for $1500 in my local CL. No idea what shape or anything about it, but fore reference/comparison purposes.

I actually noticed that right after I posted the comment. Good luck finding a source for a rebuilt one or even finding a company that rebuilds them. Your best bet is sourcing out a used one with documented mileage. I can't remember the OP's name, but there was a long post of a member who took is E53 4.8is to the dealer for an oil change and the technician overfilled the X, causing the engine to seize. Long story short, BMW eventually admitted guilt before pursuing legal action and he received a brand new 4.8 motor out of the crate. He could not find any companies (that I can remember without searching for the thread) to rebuild...
