So this is something I noticed while building benchmark cars for the CSR. It seems that the service cost increase with the geared top speed of the car, even if the actual top speed doesn’t change.
For example, here’s a car with a slight overdrive:
It costs roughly $1000/year to service:
However, if I decrease the top speed by ~20 kph, like this (notice how the actual top speed barely changes):
The service costs drop by $80!:
It’s even more pronounced on a car I bulit for CSR65. It’s geared for 336 kph, with an actual top speed of ~250:
However, if I set the limiter to 260 kph (mind you, not actually changing the actual top speed), the service costs drop by $200!
Is the game supposed to do this, or is this a bug?
