Electric adjustable seat retrofit???

Today I visited a breaker/seller who is selling fully
electrically adjustable leather seats (with memory,
lumbar/shoulder support etc) for E60 from 2006 MY. I have
partial electric adjustable seats but they are heated
where I am not sure if the seller's seat is also heated
but considering thats high-end seat I would assume it be
to be heated too. How tough would it be to electrically
swap this seat to my car? Would it need new wiring loom,
how big this job is going to be? I don't mind stripping
my car to bits as I have done it before and repeat
doesn't take that long, anyway I am doing cic retrofit by
end of this month so can combine these alongwith.

I can code car myself to enable almost any option so
software wise no issues, I don't need to visit dealer.

He is also selling auto folding ec mirrors (SA430), mine
is manual folding however I found that condition is his
mirror cosmetically isn't great (glass and ec bit was
good) and they are not in glossy shadowline too. So is it
possible to rip-out all the electronic bits from the
mirror and put in my existing mirror housing, I am more
worried about replacing folding motors, they are based in
the triangular mirror base place, would it be possible to
take motor out from that casing and put it in mine?

Andrew, thanks for your input here. I understand your point here that seats may not be heated, is there a way to identify if seats are heated or not? What is the yellow connector bit under the seat? I couldn't find its part number of realoem, is that for heated seat. Incase breaker's seat isn't heated, is it possible to take out my existing seats heating bit and transfer to the new seats?

I have spent hours on WDS diagram and looks like (as you said) wiring harness is same for all the E60 (LCI, non-LCI doesn't matter here) with the seat module. I have not checked heating wiring yet but will do soon. I do have seat module (quite small in size with just 3 connectors), so I think harness is already laid out. The only signal
input which goes to seat module from car is the can bus from the LMA, not sure why light module is involved here but this is how it is. In this case it should be plug and play (with some coding done and VO added to the FA).

Regarding mirrors they are exactly the same size and design as mine (different colour and no shiny bits), they just fold in the same fashion (not upwards) so I think it saves quite a bit of space on the both side, anything close will hit doors anyway. Reason I am interested in
mirrors is because first it is coming quite cheap and secondly it doesn't look right to have fully electric seat and manual folding mirror.

I can get whole lot for perhaps £500 (rear seats, door cards and mirror) I seriously doubt I can return it, even if breaker agrees to it I won't believe if he will honour it. Its kind of risk for half a grand which may be fruitful or totally useless. Confused what to do next...
sometimes this looks like opportunity, next moment it sounds total waste of money. Worth bothering?

If it were me and my money, then I'd be spending it on something else.
