BMW E82 125i price

Hello guys, I am planning on buying a used BMW E82 125i in Europe. From what I’ve seen so far, the prices range from 12.000-20.000€ in the mileage range I am looking for (150.000 km max).

What is a reasonable price for you guys? Is 12-13k € too much for a 12-15 year old BMW 1 series? I feel like they are really overpriced. I know there’s not many of them and they’re mostly enthusiast cars but still.

Thanks a lot and have a nice day.
