A thought for examining any used runner. Inspect tire date code molded into tire following DOT numbers-its a 4 digit code representing week of year (first 2 digits) & the last 2 digits of year. All 4 tires will normally be the same. If not find out why? Brand new tires can conceal alignment/frame issues. Typically tires are not well balanced or steering components aligned by dealers flipping a trade in.
If looking at Toyota Certified pre-owned the dealer will spend more $$ on detailing interior & exterior, changing under hood fluids, new tires etc. Maybe even a pad slap brake job. So do an under vehicle inspection by crawling under or a independent mechanic putting it up on a lift AND allowing you to get under it and take pictures. You can post photo on this site if you see somrthing that seems unusual.
The 50,000 mile 5 year old SR5 I bought my daughter had a nice maintenance history of oil changes. But under vehicle lubes were original never serviced. The dealer salesman said these fluids were new- but not true. I had my mechanic replace them all after we got it home after purchase.
