Question to the tax professionals: Travel book or 1% regulation?

Hello, I have read in the forum once but found no answer for my specific case. I have a company car (Passat 2.0 TDI / 190PS) to the BLP of 61,000€. The leasing rate due to all kinds of GK discounts is only 600€ gross. There is also everything there: tires, maintenance etc. in principle all inclusive. In addition, there are fuel, insurance, tax and small stuff like disc clear etc.. I can not accurately quantify these costs. I drive about 40,000 km a year, of which about 40.000 km 2x50km daily journeys to work (250 days x 100km = 25,000km). Furthermore, I use the car for about 5,000km private. Rest (10.000km) are on duty. My share of the service decreases rather than that it increases. In addition, the shortest route (39km) from place of residence to place of work is taken into account with the payroll fee 50km for the faster route (already recognized by the FA). My tax class is 5 / top tax rate (42%). The following approach: Due to the fact that I currently tax 1% of the BLP and still 0.03% for the journey to work, I have nothing of the discount, which is reflected in the leasing rate. My taxation currently looks like this: + money-worthy advantage company car (1,0 % regulation) = 610,00 € + money-valued advantage driving costs (61000 * 0,03% * 39 km) = 713,00 € = total money-value advantage to be taxed = 1323,00 € A travel book for me?
