I've had bad luck with KYB on a variety of cars. Never again.
Only ok at first, then they don't last, certainly not 100k.
You won't really save anything if they last only half as long.

For front on 240D I show:
KYB- $33
Boge- $46
Bilstein C-$70

I'd spring for the Boge. I've seen them last 100k+.
You can send your daughter to a state school, and this can be her first car. Perhaps the shocks will still be good...

Best of luck.
