A170 Petrol auto cvt gearbox needed 2005

[TISPKJ]

Hi guys, bit of a long shot but will ask anyway.

I need an auto box for the above, have been quoted circa £3k refurb which is obviously more than the cars worth.
I recently gave the car to my nephew so looking to pick up a box from breakers maybe, I understand that it needs to be mapped to the engine and needs to be the correct type.

can anyone suggest any breakers to try ?

thanks
