Yamaha Zest / Mbk Evolis = Recommendation?

Moin! I am Christian, 31 years old from Oldenburg. I am currently looking for a 50’s scooter that complements my motorcycle for the journey to work. Now in the autumnal weather I want to send the young machine into hibernation. In my search I came across the Yamaha Zest. In my youth the machine has disgusted me, but today I find that she has something… Now to my question: What does it look like in terms of quality? Especially d I’m interested in the topic of rust. After a good 25 years it would be quite conceivable that the frame has survived its best times. But I can’t tell at all. Maybe someone here has experience with this “Scooter-Youngtimer”. Let me know if you know any strengths and weaknesses.
