It's not a bad deal but i think you can haggle the price lower if you are really set on this car. Personally I would look for something with at least ~1 year warranty left on it. And the newer idrive IS a lot better than the older version
Also, just as a general tip for looking at used cars (i did a lot of research before buying my 2010) is to learn all the "tells" of what options are equipped on the car from the pictures. Always looks at the pictures, don't believe the descriptions...90% of them are wrong. In the ad you posted the description says it has a Manual transmission AND dual plate clutch?
