Firestone does PPI for like $25 and it's thorough. We've done that twice in the last year (Wexford).

First was Carvana (title/reg was not a problem on that-- cash purchase makes it easy) due to wanting very specific spec and also southern car (no rust).

Second was local dealer in Wexford. Both were satisfactory experiences.

At the Yaris/Fit pricepoints you're not going to have much downside potential, they're-- no offense intended-- the most basic of basic cars. Just be VERY careful regarding corrosion and good service history as typically entry level car owners are a combination of disengaged and expense-averse.
