How many times is it advised to have comprehensive maintenance work done for your vehicle?

The correct answer for the exercise: How many times is it advised to have comprehensive maintenance work done for your vehicle? Is: At least twice a year.

Explanation:

First of all, to understand this question we need to remember what comprehensive maintenance work is. It is the complete check-up of the car systems. Drive belts, oil levels, wheels balanced, tires grip, air, etc. The reason why this has to be performed at least twice a year is that even though many of these systems can perform ideal work for more time without being reviewed they could be damaged over time by small almost no meaningful events but can develop into high and very important impacts into the car. For example, wheel balance can't be affected by small bumps, but if small bumps happen all day all days we are going to see an impact in the car that can derive in a balance loss and eventually a big accident.
