Hello, I’m offered a cheaper Mercedes 250 SE from 1966. Oil consumption is 0.5 liters per 1000 km. Condition is VERY good according to the age. Consumption according to the seller is 11 liters per 100 km. Can one still move such a vehicle in everyday life (but not winter with snow) or is that too risky. It must be very reliable. What do you think about it? MfG Lucas Jensen
