Finally some good news! Today I took the whole day off specially for driving the van to Vauffelin, Biel to show it at DTC (Dynamic Test Center). It all worked out perfectly, 1.5h investigating the rims, wheels and axles, and everything  photographed and completed with a small test drive.

The weather was beautiful, the air was cold, 120km/h too loud, 80km/h just right for cruising.
