Robin's communication skills have been discussed at length in previous reviews. For my part, I can only confirm them. For my part, a great start was already made by actually considering the youngtimer BMW X3 that Auto Arp had for sale as reserved, when I announced my planned visit 2 days in advance (so as not to have to make the approx. 2-hour drive to Bleiswijk for nothing).
After an extensive test drive the purchase was closed, with some agreements about points that still needed to be addressed on the X3 imported from Switzerland. The communication may indeed be good, but at least as important is the observation that agreements are "just" kept. In short, they do what they say. Auto Arp stands for Youngtimers with old-fashioned service.
