Well. You need not drive/rippppp the M3 just because it's there.
Since you yourself admit
- it's a waste on you
- you can have it for a long period
- in the isolation of the alps
- unsupervised
I'd recommend.
Take it apart !!! From an ICE POV. Do a thorough analysis of the acoustics of the car and go back and give BMW tips on how to revamp the stock M3 ICE (I presume it has one?).
They might be so delighted, they'll present you with a M3 for use in India
