Hello dear municipality, thanks to the powerful car lobby, it has been legally mandatory for more than 5 years to use only factory-made taxi vehicles for the registration of a taxi. Before that it was feasible to convert used vehicles to taxi, now it is necessary (usually) a sogen. Certificate of conformity, which e.g. for oldtimers are not created. Only possibility – because of the inventory protection – would be the (re)commissioning of a before – or always noc h – registered taxi vehicle. If someone still knows a (immediate) registration possibility or knows how to buy an old taxi, I will gladly pay a good brokerage commission if I succeed. Thank you for your efforts and greetings, Mike.
