✓ What they do well
1 thingDoc fee is in line with the market
At $180, their doc fee sits at or just under the IA average. Not exceptional, but nothing to fight over.
! Where to push back
1 thingListing price and real price disagree
Quoted prices run 8.4% above the advertised listing — roughly $2,940 extra on a $35k vehicle. That's a pattern, not a rounding error.
TipThis dealer's listing price is a marketing number, not a real one. Don't anchor to it — anchor to an out-the-door target.
