Car Buying Battle Plan

The sticker price is the least honest number at the dealership.

The Car Buying Battle Plan is a complete car-buying spreadsheet that shows you what each car really costs over 5 years, decodes every dealer fee, values your trade-in, and gives you the exact words to negotiate with. Open it, delete the sample data, and walk into any dealership knowing more than the salesperson expects you to.

What is inside (8 tabs):

• START HERE: setup guide and FAQ so you are running in 5 minutes
• TCO Comparison: compare 3 cars side by side. Price, down payment, tax, fees, APR, insurance, fuel, and maintenance roll into one 5-year true cost per car, with the best deal highlighted automatically
• Loan Calculator: monthly payment and total interest from any rate, term, and down payment, plus a reality check that flags when a dealer quote is higher than your math
• Dealer Fee Decoder: 12 common fees explained in plain English, each rated Legit, Negotiable, or Junk, with automatic OVERCHARGED alerts when you enter a quote
• Trade-In Worksheet: valuation ranges, dealer offer tracker, and the math on whether to trade in or sell private party
