Even for this popular old car model, spare parts will be a problem. If the car is in India or Pakistan, there will be absolutely and totally zero spare parts problems. They can even fix the leaking seal for the excavator's giant cylinder/piston leaking seal without proper spare parts. The plus thing is that they can come up with a solution. The minus thing is that it wouldn't work at optimal efficiency and it wouldn't work for long. India or Pakistan can repair anything under the sun and moon even without proper spares and tools. I take my hat off to them.
The engine compartment is very spacious. Very easy to dismantle carburetor, starter motor, belts .... The newer ICE car engine compartment is extremely compact.
Not to mention the hair-brained computers they're putting in the new ones! At least offer an open-source version
