German cars are usually very expensive. And you'll find a lot of (c)rusty cars that have been made to look good but are never worth their money on a closer look. Plus winters are cold in many regions of this country and salt on the road is the worst enemy of every car.

Spain and Italy might we worth a closer look. I recently saw some MK2 XR2s for sale in Spain. There's many more for sale than in Germany and usually half the price. Spain is much warmer, just be careful with cars close to the sea, especially the Atlantic.
