Hi all

Very new to this forum, this is my first post. Have been a X400 driver for many years, and in the market for an X250, likely diesel, likely just post facelift. I'm sure there are many threads in here which detail the things for new buyers to look out for, and they're probably indexed somewhere logical too, but I can't seem to find them. If anyone could point me in their direction, I'd appreciate it. If there aren't, can anyone give any sound advice on things to watch out for? I've heard bad things about the 6HP28 transmission - can anyone confirm?

Many thanks
