Why do posts about particular cars get squirrels away into a separate forum dedicated to that brand resulting in literally zero replies. Even if it is a significant car worthy of discussion. Whereas generic car posts can safely remain here and get lots of replies?
Probably because they don't want the GG section polluting with loads of random little questions around particular models as that's what the other sub forums are for..
If you don't get an answer on the those then there are many other brand specific forums on the web to engage with.
