I have only been to Norway a few times but the scenery is absolutely breathtaking in many places. The Tourist business is florishing and there are a lot of places Worth visiting. If you only have a short time its difficult to choose.
My favorite drives are around Hardangervidda and Geiranger - Trollstigen.
