The 190E is a pretty durable car and a very safe one, too. I'm assuming its a 2.3 190E and not a 2.6? The 2.3 is pretty good with mileage and the engine is very easy to work on. The 2.6 offers better performance, but at a price of a little worse mileage. The 190E/190D is still used as taxi's in some parts of Europe to this day.
