The full story
Why Fox Valley GMC earned this grade
Between March 2026 and August 2026, CarEdge negotiated or logged 4 verified deals with this dealership. We pulled the doc fee, the add-ons, and the gap between advertised and out-the-door price from each one. Then we graded them the way a friend in the business would: on the things that actually cost you money.
✓ What they do well
1 thingAdvertised pricing is largely honest
On average, the quoted price is only 0.9% above the listing — small enough to be fees, not markup games.
! Where to push back
2 thingsDoc fee is slightly padded
$387 is $19 above the IL average of $368. Not outrageous, but worth questioning.
TipAsk them to match the average. If they won't, factor it into your overall price — every dollar here is negotiable.
Mandatory add-ons show up on most deals
50% of quotes include add-ons presented as non-negotiable, averaging $553. Expect them to try to include something — paint protection, nitrogen-filled tires, VIN etching.
TipAsk which items are genuinely required and which are dealer-added. Anything not required by the manufacturer or the state is worth pushing on.
