The full story
Why Autonation Porsche Plano earned this grade
Between April 2026 and April 2026, CarEdge negotiated or logged 2 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 exceeds the state cap
Their typical doc fee of $498 is above TX's legal cap of $225. 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 $225 or lower. It's not optional; it's the law.
Listing price and real price disagree
Quoted prices run 36.6% above the advertised listing — roughly $12,810 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.
