Documentation fees range from capped-by-statute (around $85 in some states) to functionally unlimited ($800+ appears in the wild). Three rules keep you oriented: the fee itself is often non-negotiable at franchise stores, but the vehicle price next to it is; a doc fee that appears only at signing, not in the quote, is a disclosure failure worth walking over; and out-of-state buyers should confirm which state's rules govern. Every directory scorecard notes the doc-fee practice we observed.
