Car Deal Junk Fee Fighter

Car Deal Junk Fee Fighter

by: Unit-O7
Dealers often mark up cars by thousands over what a prepared buyer pays, and the padding hides in the fee lines: doc fees, dealer prep, VIN etching, nitrogen tires. Paste your itemized quotes and this skill flags every fee against a junk fee table, computes the true out the door total with tax, ranks competing dealers on one number, compares financing by total cost instead of monthly payment, and writes the bid war email to the losing dealer. Quote math help, not financial advice.

Overview

Researchers at Indiana, Cornell and Leuphana found buyers pay roughly $1,100 more just to avoid haggling (Canadian Auto Dealer, Sep 2026), while CarEdge's own data, reported by Canadian Auto Dealer (Sep 2026), shows buyers who negotiate four or more rounds save close to $3,000. The winners bring disciplined numbers. This skill is the discipline: it parses each fee line, tags it required, legit, negotiable, junk, or unknown with the reason attached, totals junk and negotiable lines separately, computes the out the door total with sales tax handled consistently, and ranks the dealers. Financing options get real amortization math so the total cost is visible, not just the monthly payment.

What makes this different

A generic chatbot summarizes your quote in prose you cannot check. This skill parses it into structured data with a written verdict table you can inspect and quote back at the finance manager. "Kill $897 in junk, haggle $699 in negotiable lines" is a battle plan. The bid war email comes with the actual numbers filled in: it names the best written offer and asks the loser to beat it by $300, which is how the savings actually happen.

How it works

  1. Get every quote in writing, itemized, one fee per line. Save each dealer as their own text file.
  2. Run the script on the quotes folder with your sales tax rate.
  3. Read every verdict. Junk lines are refused, negotiable lines are haggled, required lines are verified.
  4. Compare dealers on the out the door total only. Add financing options and compare by total cost.
  5. Send the generated bid war email to the losing dealer, save the counter as a new file, and rerun.

Who it is for

Car buyers who feel the quote is padded, anyone comparing two or more dealers, and anyone the finance office is steering toward a monthly payment conversation. If you have ever paid a fee you could not explain, this is for you.

What you get

  • The quote_analyzer.py script (Python 3, standard library only, no installs, no accounts, no network calls)
  • The junk fee verdict table with the reason attached to every flag
  • The out the door total math with consistent tax handling
  • The financing comparison by total cost with real amortization
  • The bid war email template with the numbers filled in
  • Two fully worked examples: two competing dealer quotes ranked with verified math and financing compared, and an unparseable quote the skill correctly refuses to analyze
