Company car Passat, A4 or BMW 3

Hello dear Motor-Talk community, I would need your advice, as I can order a company car and with the many possibilities in terms of model and equipment variants a bit overwhelmed. Never had a company car and before I drove an old Honda Civic. 🙂 With the car I will mainly take rides to work (30km easy). With a few private rides I might come to 15-20k km a year. Currently I have a 3 BMW Touring as a loan I have more than 500 € net as a deduction. That’s actually too much and I wonder if the company car is worth it at all. Apart from that, I find the BMW quite great! Is it going great, looks chic and the equipment is top. Because of the high tax burden, I got into doubt whether the car is worth it for me at all. I think, however, that I am because of the many advantages (company) A4 Limousine Attraction 2.0TDI multitronic 110 kW Passat Limousine Comfortline 2.0l TDI BlueMotion 103 kW/130 kW 320d Limousine Aut. “Eff. Dynamics Edition” Minimum equipment is: Diesel, Automatic, Navi, Business Package Special equipment I would have to pay at my own expense (but with discount) myself. I have no children and I am single, from dahe I don’t really use a big car. However, it is important to me a high level of seating comfort, as I am quite large and have problems with the intervertebral disc. Can you recommend me a car and give me a tip, which special equipment I should not miss? Thank you!
