Trade-in and warranty bundles: compare the whole transaction

All guides

A larger trade-in credit is not necessarily a better deal if price, extras or interest also increase. Buying a warranty does not automatically create trade-in value.

Separate the trade-in from its debt

Ask for the trade-in value, exact loan payout and replacement-vehicle price separately. If debt exceeds trade-in value, identify the negative equity being transferred.

Revenu Québec says qualifying trades between a non-registered individual and a registered dealer reduce the GST and QST tax base. QST also considers estimated value where it exceeds the sale price. Verify your circumstances; a private sale does not automatically receive identical treatment.

Compare complete offers

Request itemized transactions with and without a trade-in, then with and without warranty. Compare price, actual applicable taxes, down payment, transferred debt, principal, rate and total interest.

A warranty can have exclusions, deductibles and transfer conditions. Do not assume it increases trade-in value or pays for itself.

Your checklist

  • Get a valuation and exact loan payout.
  • Separate trade-in, optional products, taxes and negative equity.
  • Compare complete totals using equal loan terms.

Worked example

Hypothetical pre-tax example: offer A, $30,000 car minus $10,000 trade-in = $20,000 difference. Offer B, $32,000 car minus $11,000 trade-in plus $2,000 warranty = $23,000. The larger trade-in hides $3,000 more before interest.

Limits

This is neither a trade-in valuation nor a tax calculation. Only written terms and the applicable transaction rules support a conclusion.

One question, if you wish

Do you have a trade-in and an itemized offer to compare?

No answer is required. You can save an answer for your advisor in the interactive version; reading does not share anything with a dealer.
