Hello together, a friend of mine gets a new company car (Monteur) and would like to use it for a bit also privately. Because of the very commercial character of the vehicle (Mercedes Vito with extension for tools) the 1% regulation of course does not come into question. However, it is also previously unclear how exactly the journey book method is calculated. There are countless computers and information on this on the net, but there are information needed, which are not known before od BLP: 32.750€Distance to the company: 30km (However, this route is driven as good as never, since it starts every day directly from home to the respective – changing – place of operation).Does this still have to be taken into account?Running maintenance costs: ??? Since he has to go to other places of operation every day, sometimes near, sometimes far, the maintenance costs change continuously. e Vitos (so far always VW bus), so there are no past values to this model.Share of private trips: he does not know this before. This can be only 50km p.M. or 200km. What value do you put on this? Thank you for your help!
