First, the website did not let me put the Marine in the basket in size m... I think this is the reason why it was still available for that price. After contacting the guys from the shop via email, they fixed that and I could buy it
I have bought the Marine with additional mud guards plus a lock for 300 bucks alltogether. That is a bargain I guess!
Thanks a lot for all your help guys, I really appreciate that.
Cheers!
