The MB OEM crossbars are the best deal at $305, but I preferred the Thule aftermarket Aeroblade Edge. Comes in black to go with Night Styling package Doesn't sit up as high as factory bars..$495 retail.
I would avoid the MB bike holder. That's not the preferred setup these days.
My favorite would be a Yakima upright mount like the Frontloader for $179. You don't remove the front wheel.
FrontLoader | Yakima
Second choice would be the Thule 594xt Sidearm Upright for $199.
Your tire will fit either mount.
Fork mounts are cheaper if you don't mind removing your wheel and tossing it (dirty) in the back.
