That's a different blue one, the guys i sold mine to are very happy with it.
There are 2 180hp 5.1 for sale on mobile.de and they both have red "D" on the badge like the Cali 180 hence my reasoning.
Regarding the C. Joker, what worked for us was the high top, top bed, skylights and windows, bathroom/toilet, kitchen, larger awning, ice box, hot water, int lighting.
Negatives for us was rear seat/ downstairs bed. Not very comfy for lounging in and smaller space than Cali in this area. Smaller downstairs bed and not suitable for 2 adults. My son really disliked it as both a seat and bed compared to the Cali. Storage space is challenging but doable. Lower spec cabin/base van.
All in all, perfect for a couple in our eyes. For more a Hightop Nugget Plus would be better.
A high top van sub 6m is perfect but very hard to find.
