I’ll congratulate you on your good purchase when I see a video on how the doors open freely.
I would not dare to supply my fellow Twizy owners with goods from China cause I will want to be able to refund them if something goes wrong. And China sellers won’t back me up in such cases.
In addition how long will a china part work properly? My struts are pushing proud a third year without any claims.
In most countries customs charges will be a surcharge to consider.
