You only have to travel to Western in Edinburgh to actually buy a new ALFA but if it's future servicing you're worried about Arnold Clark at Springburn Road still do ALFA servicing and have a used ALFA selection. And any VAT registered garage can do your routine annual servicing.
I'm sure Western SAAB in Tradeston can do your servicing if you really want to have Western service your car.
As for there being an ALFA dealer in the west.......I wouldn't hold my breath.
