Need some suggestions for a nice route? 
You in East or West?
NE, just north of Aberdeen.
As for a route, if you want to research a cracker...try heading for Blairgowrie, then over Glenshee to Braemar, then towards Ballater, head over the Lecht on the infamous Cockbridge to Tomintoull road, then Grantown...you are then deep in Whisky country...just drive anywhere round there. It's sublime.
Cockbridge-Tomintoull, probably the best road i've found in the UK:

Even in winter, us northern types attack it with enthusiasm...

For a really good drive, from there, head for Inverness, via Carrbridge/Aviemore, go down the side of Loch Ness and pick up some of the sublime West Coast roads back down towards Glasgow.
Aww...those pictures are making me sorry to be stuck offshore!
Anyway, I digress...
