User blog:Mr Procrastinator/How often does a car need servicing?

In the servicing menu,  it can be seen in the car condition bar that every car has 7 red 'bars' and 17 green 'bars'. If the car condition goes into the red, then the car loses performance.

From testing, car condition decreases at a rate of 1.25 'bars' per kilometer driven. It is independent of car damage, speed driven or time taken. This means a car can be driven 21.25 km before it needs servicing.

However, driving off-track will decrease car condition much more rapidly. A rough estimate is that driving off-road decreases at a rate of 8.75 'bars' per kilometer driven, a 600% increase. Note that this includes ANY driving off-track, even if two wheels are off-track but two-wheels remain on track. Driving off-track is accompanied by an off-road sound effect to warn a player.
