Very small thing. I'm selling a car right now on carsales.com.au and overall it's a solid experience. What I notice after a bit of usage however is how bad the sites <title> tags are.
Many pages are literally just Car for the title. This is apparent on the Manage ads page. I assume this might be because some of these pages are being client rendered and they're just shoving something generic into an index.html that's injected with what looks like Angular.
