The full story
Why Bill Kay Chevrolet earned this grade
Between November 2025 and April 2026, CarEdge negotiated or logged 5 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 2.2% above the listing — small enough to be fees, not markup games.
! Where to push back
2 thingsDoc fee is slightly padded
$403 is $29 above the IL average of $374. 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.
Add-ons show up on most deals
60% of quotes include dealer add-ons, averaging $1,559. Expect them to try to include something — paint protection, nitrogen-filled tires, VIN etching.
TipNearly all aftermarket add-ons are optional and removable. Say "please take those off the quote" and watch the OTD drop.
