Decision support: company car, yes or no ?

Hello everybody, I can imagine that there are already a few topics on this topic, but I’m not really getting through on this issue yet. Brief description: I now have the opportunity to decide between a salary increase of 650,- € or a company car. At the moment I earn 3100€ gross, am tax class 1. So I would get fixed 3750,- € gross. The company car can cost up to 50,000€ and must be either Audi, Mercedes, Or BMW. The employer wears here with everything, fuel for private trips, workshop, inspection etc. This financing then runs over the 1% regulation. At the moment my work path per route is 50km and I drive a 10 year old golf with something over 100,000km. What would you advise me to do? I find that the deductions by the company car are enormous and am not sure if I am cheaper without company car. Can you help me ? P.S I would like a Mercedes CLA for a good 37,000 € very much, which also allow t.
