This would have several advantages:
* Help people get help for their cars, since cars that share the same platforms tend to be about the same age, and have the same engines, transmissions, maintenance, problems, etc.
* Future-proof the forums, so that the list doesn't keep growing with every new model - there will be more SPA and Global C cars, so the list will keep growing...
* Help keep the forums active. There are too many forums to check them all individually, even if the person may have knowledge that would help.
The above way of doing things just makes way more sense IMO. Because mechanically the P2 cars are all pretty similar.
I go to the S60 forum sometimes as well now. But there's still stuff unique to the S80 that definitely gets overlooked due to the small size of our community here.
