Does the car wash actually wash the car?
In the Gran Turismo series, does the Car Wash washes the car or is it only a fake car wash? I don't remember that the cars got dirty and I don't remember seeing a difference before and after going to the car wash.
Solution 1:
It actually depended on the game you played on.
If I remember. the first one does not do anything special. Hence, its a fake car wash.
However, in the second game your car could get dirty, but it never effected performance.
In the third game and up, it starts showing dirt and grime; and that dirt and grime does start affecting performance, mainly in aerodynamics (for example, similar to if you put a spoiler on the back and turn the settings all the way down).
Also, note that car washes got cheaper later in the series, giving way to be more a part of the mechanics of real life.
Solution 2:
I've always wondered the same question.
It seems that after a race your car will lose a little of it's luster. Bring it to the Car Wash and it gets all shiny again. But ain't worth it for $50M.
Solution 3:
Not that noticeable, but it does get shinier. The car's paint does get slightly dull if you drive it a lot, so unless you drive that car for hours I don't think there will be any noticeable differences.
The newer games (GT5, GT6) really make the car look dirty, though. Not by DiRT standards of dirty if you take it off-road, but there will be a lot of noticeable dust on the car if you drive it around a lot without taking it for a wash.
