After 4 years of loyal service and no failures or defects we changed from the Q2 to the SQ2. Reason: we drive a lot into the mountains and the Q2 is nice and everything, but a little emotionless and with “knappem” overtaking on mountain roads simply lacked the passage. In addition, we found the chassis a bit soft. Sure, it is all top, but the “joy” was missing something. The small changes on the new model do not make out, it remains unique everything as it was And that’s a good thing. ABer the extra power and the tighter chassis really bring it over. We could have kept the Q2, but some emotion needed in life. And the new one is bright green, as a counterpole to the Black/Grey/Silver Flood.
