I had a '63 220Sb, drove it for a bit and sold it. The fellow who bought it hired me to rebuild the engine, then a few years later he scraped one side against a guardrail. So he bought another one with a tired engine, put the fresh engine in that, and still uses it after almost 20 years. Great cars. But if you want maximum cost/benefit ratio for what is really an appliance, the Japanese cars are the best.
