Apllication of component updates

[Arakash]

I never thought of the modify button as something which would cause major enough design changes that would require you to redesign a vehicle.
I was thinking of the manufacturer making changes based on customer and mechanic/technical feedback on the vehicle, like changing a seal, modifying timings etc..

If you can think of an example of where/how this happens in real life and to what part of the vehicle, id be much appreciated. As you can see im having some difficulty following it

I'll give it a go but I'm not 100% sure exactly what you're asking.

Commodore (an Aussie car for you non-Aussies playing along at home) would be a good example of a car undergoing minor changes based off experience learned in the marked and being re-released as a new year model. Ever heard the term "Series II"? This is what Holden does to keep their cars up to date between complete model overhauls. They generally make any necessary changes as one big alteration and put it out as a "Series II" then leave the car mostly alone until the next model.

BMW would be a good example of the opposite. Every time I took my Bimmer into my mechanic with a failed part he's complain about how BMW constantly change things on their cars and it made it hard for him to know which part he needed. This was generally smaller components like oil pumps, powered window winders, fuse boxes etc. The overall car was basically the same through out it's life but but there were constant component upgrades going on under the skin.

I was rambling a bit there But you gave me basically exactly what i was looking for there, thanks.
These are the kind of examples i was hoping would be brought up.

The thing that i was wonder/had me confused was that i thought companies, like Holden as you mention, made minor changes to their production models during their production run, which were basically applied to that design as it was still being produced. You gave some good examples of that there.
So if that was in Gearcity, i assume it would look like:
The same design produced 3 years later would have undergone some minor improvements while being produced at factories without requiring a redesign.
After this discussion, I believe the modify system for whatever reason doesn't do/cover this. This raises the question of exactly what it(the modify system) was supposed to represent in Reality.

I suppose ill have to see what Eric says about it when he has time to make a post.
