Talk me into/out of buying this 10 year old 330k km BMW

So, for a 2014 2 series coupe 220d m sport, this guy is asking 13k negotiable. It's done 334,000 of supposed highway kms which has full service history. These cars prior to 2015 are known to be quite reliable if you excuse the timing chain and water pump issues, assuming they have been repaired over this amount of driving however, would this potentially be a good idea to get the want for a BMW out of my system? Would love to hear others opinions, naturally I'm expecting regular BMW service costs.
