Which used scooter as a third-party vehicle?

Hello together, I am mainly a railway driver, use my car rather on private trips and otherwise like to ride a motorcycle. Now I would like to buy a used scooter for the city as a third vehicle, possibly also for a somewhat extended area of use. However, with the variety of the offered models it is difficult for me to choose. My considerations are: – Not too expensive (max. 600 – 800 EUR) – Max. 125 cm3, possibly also 50 cm3 – Wendig and not too large – 2 seats – Storage space or luggage racks – Easy to repair, robust technology – Precise appearance (Not absolutely beautiful in shape, but no “sporty” youth scooter, not an all-world model) – No Chinese factory I would be very happy about a few recommendations!
