Hello.I wanted to tell you my experiences with the above mentioned company.After a few phone calls with the company I decided to have a exhaust for my 129 he built.To and fro and “all no problem etc…” I entered on 31 August the trip to Erftstadt to hubert-vilz-platz 8. arrived there first I had to find out that under house number 8 only a run down factory house stands. next to a wooden gate which was locked. no ring, no company sign u. sw.mir swan already something like that. point nine clock came then lord seriously with the car around the corner and we meant we had to drive further to the manufaktur when I approached him ( had asked on the phone whether the workshop is under the address, which he affirmed! ) he did not go further on. we then drove to the “manufaktur “. a few km further at zülpich. there we turned then into a farm where it looked like with an east block lpg.da I was first a bit baff. there he asked I said thank you and asked for the cars where we could listen to the different systems as discussed by phone in advance.. therefore he said there were no ones and the exhaust would be already finished we are then in the “manufaktur ” ( bkk exhaust) and have and looked at the exhaust. was not like in the internet to see with flange (” we don’t want to do anymore because the people want cheap and the anyway only break etc ” ) , But to get stuck.For that the production exhaust had to be cut. if I didn’t want to have someone else the exhaust would have stayed there. what disturbed me then was that the exhaust was still pointed without the battery to be clamped off ( ” would happen nothing, have done so many things etc ” ) Lord was already serious for a long time again somewhere on the road. conclusion: Lord serious is only mediator. who believes at hubert vilz place 8 stands a beautiful workst att with big gates will be disappointed. I personally have been lied to when I asked if the workshop is also under the address as well as with the 3 cars which should be listened to. will do the devil there again something to buy or recommend someone. so long mario
