Hello, new member, personally find this website the most infuriating of all the forums that I have been in so far . Trying to purchase a W204 C63. I have seen what looks like a decent one on here for sale but now saying that I can't message or reply to the thread of the seller . And I can't message anyone on the forum..? Very odd. I can't see commenting on 30 posts very time efficient when trying to buy a car.. plus I don't own a vehicle yet.. so don't see how I could add to a constructive discussion as most questions are already answered on here.. Really odd setup..
