Consumption considerations / Comparison

So, my Alfa consumes 15(+-1) liters/100km of super gasoline. Granted, can you live with it? I mean very well, because for a comparable Audi A6 Avant 2.4 I would have had to pay twice the purchase price, of which I convinced myself at mobile.de again today. With me this difference is approx. 12.000 € ! If I assume that the Audi consumes only 10 liters/100km, then I need with a driving performance of 10,000 km/anno with my Alfa 1800, with the Audi 1200 Li 1.20 €/liter causes a difference in the consumption costs of 720€ in favour of the Audi. However, taking into account the financing costs for the acquisition additional costs of the Audi from 12.00€ with 5 %, then the additional costs per anno are reduced to only 120€. M.a.W. Only in 100 years the break-even is reached (12.000/120), only then will the Alfa be worse in the consumption costs than an Audi. Irony with it, but a well-preserved Alfa will then be much more be worth as an Audi and my great-grandchildren will praise my farsightedness 😉 saluti!
