All right, call me prejudiced, but:
The Austrian Alps. Everywhere you go, instead of east-north-west-south it's only up or down. Winding roads and great scenery.
And then, when finally after about 45

years you've driven all passes and backroads, it's a half day drive to the south to visit gambalunga at Lago di Como for some great food. With the great opportunity to go back home via Switzerland.
More passes...
