320i e93 (n43b20) vacuum pump change

Hello e90post,
yesterday I checked a 320i cabriolet that I'm considering buying. The car has done 72k kilometres (43,5k miles) and has the N43B20 engine with 170bhp. I didn't notice any signs of an oil leak but many of the horror stories on the internet got me somewhat worried, so I thought about taking some precautions. When's the right time to change the vacuum pump to avoid major leaks on one of these? Should I do it right away?
Thank you for your answers.

Not heard of any major issues with vacuum pumps. It's only function is to create vacuum for the brake servo. I'd leave it alone...
