The full story
Why St. Mina Auto Sales earned this grade
Between October 2025 and July 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
2 thingsNo dealer add-ons detected
Across 5 recent quotes, we haven't seen a single "dealer accessory," "paint protection," or "theft deterrent" line item. That is rare, and it is good.
Advertised pricing is largely honest
On average, the quoted price is only 0.4% above the listing — small enough to be fees, not markup games.
! Where to push back
1 thingDoc fee exceeds the state cap
Their typical doc fee of $128 is above CA's legal cap of $85. This is a red flag — every dealer in the state must stay at or below this number.
TipTell them you expect the doc fee at $85 or lower. It's not optional; it's the law.
