The full story
Why Guaranteed Motor Cars earned this grade
Between August 2025 and July 2026, CarEdge negotiated or logged 14 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.
! Where to push back
2 thingsDoc fee is slightly padded
$377 is $6 above the IL average of $371. 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.
The listing isn't quite the price
Quoted prices run about 7.0% above the advertised listing. On a $35,000 vehicle that's roughly $2,450 in extra fees or markup.
TipGet an OTD quote in writing before you visit. Compare it to the listing — if there's a gap, ask them to account for every line.
