Only 17% of quotes include dealer-installed add-ons, averaging $995 when present. Most shoppers here never see them.
Advertised pricing is largely honest

! Where to push back
1 thingDoc fee is significantly inflated
$999 is $283 above the NJ average of $716. That's pure margin for the dealer, not cost of service.
TipThis fee is mostly not "standard paperwork" — it's profit. Push back, or get the equivalent off the vehicle price.
