It was Subaru Docklands that I asked at - twice. All they do is write the paint code (PAK) on a postit and send me on my way.Ours isn't a common colour so ordered the OEM paint pen from the nearest Subaru dealership. It arrived overnight and was only $25. Very easy to use and has the 3 step micro-sander, paint and clear coat all built in. Touched up 2 stone chips on passenger side doors and a scratch on the door sill.
I call ?? that your dealer can't get it in for you. Especially if you've given them your colour code (eg ours is M2Y), from the compliance plate under the bonnet. I've heard there's 2 versions of the orange colour, so the paint code is important. Subaru Docklands in Melbourne has a store on eBay and ship around Australia. Perhaps you could message and order from them instead?
Sadly, I have seen an early model XV in Orange on a used car lot and was shocked the clear coat was already lifting on the bonnet and there were small dents, chips and dull spots on every panel. It clearly hadn't been loved by it's owner and the car yard hadn't made any effort to schmick it up. Still, it was a shock to see such a sorry specimen. ?
