Hello Leutz 😉 I play with the thought of getting a Calli V6, have already one at hand, but he already has almost 250tkm down, but runs like a clockwork and goes according to Tacho also up to 250km/h. Now my question, how stable are these motors have made up to now only experience with the c20ne and they run with good maintenance also over 400tkm. Does anyone have information about usual flaws or weaken? About info I would be pleased. LG Mettyblau
