Financing cars and applying for credit

I want to finance a car Tuning and financing costs For example 20,000 euros for the car And 10,000 euros for the tuning I want to pay the 20000 € within 20 years But I have only seen 10 years or 12 years My question also goes 20 years And if I go to the bank and 10000 € as a credit request goes that also 20 years So I have paid the 20 000 + 10 000 within 20 years That results in a monthly rate of a total of 125 € so I could live Now I would like to take another loan An amount of about 50000 € I would also like to pay off within 20 years My question is I can allow this with my professional situation etc I have been working for a year now So over 12 months And earn about 1200 € net What do you know about these three different points what gives the bank here and what not again. 1 car finance from 20000 € 2. credit from 10000 € for doing ning And €3,50000 for a business [Transferd by motor talk from the topic ‘Financing car and applying for credit’.]
