Your car has a 1.8 liter engine. The earlier 316 had a 1.6, which is where the confusion comes in. The early 318 had a 1.9, and the later had a 2.0.
The mileage is not that bad, but if you are not in a rush, you may want to check around and find a car that has gone through less for the same money.
I don't know what the pre-owned pricing is like there, so €14K sounds like a lot to me
At around 100k, you may want to see if/when the radiator was changed, as well as other cooling system components.
