@ Alien Engel: Thank you very much, that is very friendly :-)

@ P. Stephenson: I know the Haidu Volan buses since 2 years. Last year I asked there and got some pictures, but the shape of the buses was horrible. This year I asked again, but they never answer.

About BKV buses I have heard, that they are not in good condition too. But I cannot prove certainly, so I just have heard. I just have looked to your link and I saw, that they sell 260.43. Means "komplett", that the buses are driveable and any compontents are still in it? Whom I can ask for questions? The mail address at the bottom below the list of buses? Or will you advise against buying BKV buses?
