Up your budget to say 12k.
Get it in cash and keep it with you.
Craigslist and Facebook Marketplace, check it every hour. Be ready to go, NOW.
Use several search terms. Four runner, 4runner, 4 runner, etc.
I bought my 4runner in the Denver area and did these things. Guy couldn't believe no one had even come to look at it. Didn't have the heart to tell him that spelling out Four Runner doesn't show up in searches and his location was just outside the search area for Denver.
Good luck, keep us posted.
