Search fatigue

I thought it would be much easier to find a 25-26 Acura MDX A-spec advance with 15-25k miles with the blue exterior/black interior. While i have found a few, most are 3-5k outside my price range OTD. How do people stay calm when used car shopping? I dont have any rush. 2 paid off cars and nothing pushing me, just have done all the research and found what i wanted. Just the longest wait of my life.
