Thanks,
I'm afraid I can't. I'm only 20, so still a few years away...

Closest I've been to an M3 was when I walked past two of them to get to my A3 last time I rented from Sixt
But I just tried a couple of dates through this link, and they came up. Not cheap though, around 178€ for one day, with 250km.

Which station are you using?
