- 2Effective monthly cost. AutoFinder calculation: $5,751 due at signing plus the remaining 35 payments of $751 ($32,036 total), divided by 36 months. Excludes taxes, title, registration, and any excess mileage or wear charges. For comparison only.
- 3MSRP and invoice price. MSRP is the manufacturer's suggested retail price for the trim shown and may exclude destination charges, options, and dealer-installed accessories. Invoice prices are estimates of dealer cost from AutoFinder's vehicle data provider and do not reflect holdbacks, incentives, or regional pricing. Potential savings is MSRP minus estimated invoice. Dealers set the actual selling price.
- 4Estimated lease payment by trim. AutoFinder estimate made by scaling the advertised Pro payment by each trim's starting MSRP. This is not an offer from any manufacturer, lender, or dealer. Actual payments depend on residual value, money factor, incentives, credit approval, and dealer pricing, and exclude taxes and fees.
- 5Finance payment estimate. AutoFinder calculated $945 per month by financing $47,744 (the advertised MSRP less $5,751 down) over 60 months at 7% APR with $0 applied for a trade-in. These are AutoFinder's assumptions. This is not an offer of credit, not a quote from any lender, and not based on your credit history; your actual rate, term, and payment will differ. Excludes taxes, title, license, registration, and dealer fees.
- 6Typical lease and deal rating. Median ($789/mo) and range ($572–$991/mo) of estimated lease payments across Sierra 3500HD listings AutoFinder tracks. The deal rating compares the advertised payment to that median and is for comparison only.
