Hello friends, after I had not been able to make friends with the optics of the Faclift model, the exact opposite has occurred at the moment. I have purchased several parts for an acquaintance who wants to do the conversion abroad, because he is resident there. It is certainly, as discussed in the forum already, a cost and benefit question, which decides whether to opt for or against the conversion. I wanted to come to know some opinions here, for which final sum the forum members would consider a conversion to be acceptable and also have themselves carried out. Of course nobody can predict the price development of the Sl, but you can still do your opinion customer. I wish everyone a contemplative Christmas time.
