LSD on an M235I or M240i

[nw28840]

I have a friend looking to buy one of these cars soon.

It's not possible to search on autotrader, pistonheads or the BMW site for cars that have the 'LSD' fitted ?

Is it currently an option on the M240I or was it an available option on the M235i ?

I couldn't see it when speccing up a new M240i on the BMW website.

Thanks,
Nick
