Any tips for purchasing a vehicle?

Hi I’m planning on purchasing a Honda Pilot touring this month (my dream car) and would like some help. Should I purchase a new/recent one 2016- 2019 or is it ok to get an older one 2009-2015. I seen some with low miles (69k) and some with high miles (121k). Any advice will be helpful, THANK YOU
