it could be a bad fuel filter and fuel pump
Its nothing!
Could be debris (leaves, rodent nests, etc.) blocking the air flow through the radiator.
One could find details on the miles per gallon a Merceded Cosworth gets with highway driving from someone that owns the car. They should be able to give an answer, also a dealership that deals in similar cars should be able to give an accurate answer.
24 mpg city i dont know highway ----------------- Expect rougly 30 MPG highway, could be higher or lower depending on your driving habits.
if the car is chugging (petrol) it means the combustion is not happening, it would either be problem from the source of electric power to the spark plugs, or the spark plugs itself might be faulty, to diagnose them check if the battery is having good charge at least 11 volts, then check the condenser, point condensers, then spark pulg change whatever is necessary after diagnosing and you are ready to go
It depends. If you do a lot of off road driving, it could happen in less than a year or two. If you do mostly highway driving on well-maintained roads, it could be ten years or more.
Could be many reasons such as bad alternator, or bad fuel pump.
It means that you are in prison and dreaming of freedom. Actually, it could mean many things ... or nothing at all.

Check the operation of the cooling fans. However, if you are driving at highway speeds the cooling fan would not be needed, therefore it could be a defective thermostat or a clogged radiator, in which case a radiator shop could clean and refurbish it. If not driving at highway speeds, the check not only the fan, but the thermostatic switch controlling the fan and the fuse/circuit breaker for the fan system
Your alternator could be going down the tubes. If I was told correctly, your rpms jump up because it is trying to recharge...
