Lets say u sold a car for 4 years and a car needs some tlc, can we do a refresh, change headlight design, bumpers, ect?
That would be interesting, update some of the characteristics of the model, and maybe separetely of the engine. Not cost as much if it was a new model since only certain things are being updated.
Exactly what i mean like for an example 2012 audi a4 and 2013 version. That would be awesome. 
One thread about this is enough.
Sorry bout tht but whats ur take on the idea?
Of course you can minorchange your steel or aluminium box with suspension rims engine and interior.
We can already do this. The engine editor let’s us revise an engine rather than build a whole new one, so I don’t see why they wouldn’t let us revise a car rather than design a whole new one.
