From the fine print

What the rules say

11 notes

Disqualifiers3

Any one of these can void an entry or a win.

  • Persons residing in an OFAC-sanctioned country (Balkans, Belarus, Burma, Cote D'Ivoire, Cuba, DR Congo, Iran, Iraq, Liberia, North Korea, Russia, Sudan, Syria, Zimbabwe, and others) or on the U.S. Treasury's SDN list are excluded.

    Show the rules' wording· Eligibility

    “Excluded countries include, without limitation, Balkans, Belarus, Burma, Cote D'Ivoire (Ivory Coast), Cuba, Democratic Republic of Congo, Iran, Iraq, Liberia, North Korea, Russia, Sudan, Syria, and Zimbabwe, and where prohibited by law.”

  • Mailers must be hand-addressed by the Entrant and each request mailed individually; bulk shipments of entry request mailers will not be processed or entered.

    Show the rules' wording· How to Enter, Mail Non-Donation Entry Method

    “Mailers must be hand addressed by the Entrant and each request must be mailed individually.”

  • Employees/agents/officers of the Sponsor and affiliated companies/agencies, their immediate families and same-household members, and inmates of a correctional facility are not eligible.

    Show the rules' wording· Eligibility

    “Entries will not be accepted from inmates of a correctional facility.”

Advantages3

Things in the rules that work in your favor.

  • Unlike most vehicle sweepstakes (which restrict entry to US/Canada residents), this one is open worldwide to anyone 18+ except Washington State residents and OFAC-sanctioned countries/SDN-listed persons — the schema here only models US/CA, so this broader eligibility isn't reflected in eligibilityDetail.countries.

    Show the rules' wording· Eligibility

    “The Sweepstakes is open to anyone 18 years or older or the age of majority in Entrant’s local jurisdiction, if older. Not available to residents of the State of Washington.”

  • No stated numeric cap on how many separate non-donation mailer requests one person can submit — each just needs its own online request and its own individually-mailed printout.

    Show the rules' wording· How to Enter, Mail Non-Donation Entry Method

    “Each eligible mailer will receive eighteen (18) Entries.”

  • The Sponsor's own donation-increment table shows an increasing entries-per-dollar rate at higher donation levels (0.72 entries/$ at $25, up to 2.0 entries/$ at $2,000) — bigger donations get proportionally more entries, not just linearly more.

    Show the rules' wording· How to Enter, Additional Donation Entry Terms

    “(1) $25 for 18 entries; (2) $50 for 40 entries; (3) $100 for 90 entries; (4) $200 for 200 entries; (5) $350 for 400 entries; (6) $500 for 650 entries; (7) $1,000 for 1750 entries; and (8) $2,000 for 4000 entries.”

Timing2

  • The free mail-in method requires an ONLINE step first (submitting a request on the Sweepstakes Site to generate a QR-coded mailer) before you can print and mail anything — you can't just hand-write a card from scratch like most sister sweepstakes.

    Show the rules' wording· How to Enter, Mail Non-Donation Entry Method

    “after you submit your request, you will be redirected to an Alternative Method of Entry page with a QR code. Print this mailer, follow the mailer instructions and mail postage paid”

  • The mail-in receive-by deadline is not a fixed calendar date — it's '5 business days' after your individual postmark, capped by the Sept 30, 2026 Sweepstakes Entry Period end. Mailing near the deadline risks the 5-business-day window pushing past when the Sponsor actually processes it.

    Show the rules' wording· How to Enter, Mail Non-Donation Entry Method

    “mailers must be postmarked during the Sweepstakes Entry Period and must be received by Sponsor within five (5) business days thereafter.”

Costs1

  • If the winner chooses the physical vehicle rather than cash, they must pick it up or arrange delivery themselves (only cash prizes are shipped by the Sponsor via mail/wire transfer).

    Show the rules' wording· Selection of Winner

    “Prize winners must pick up their Prize(s) or arrange for delivery of their Prize(s), except the Sponsor will deliver cash Prizes to Prize winners by U.S. mail, wire transfer, or other mutually acceptable means.”

Oddities2

  • The advertised $400,000 Mercedes-Benz SLR McLaren / $250,000 cash prize is contingent on the campaign raising at least $2,000,000 in donations. If it raises less, the winner receives only 25% of whatever was actually raised — potentially far less than either headline figure.

    Show the rules' wording· Prize

    “In the event less than $2,000,000 in donation proceeds are received during the Sweepstakes Entry Period, the Sponsor will award 25% of the total donation proceeds to the qualified selected winner.”

  • Winner notification timing is internally inconsistent: one clause gives potential winners 30 days to respond to notification, but another clause says failing to respond to 'the initial verification' within 48 HOURS of notification may cause disqualification.

    Show the rules' wording· Selection of Winner

    “Failure by potential Prize winner to respond to the initial verification, or failure by Canadian Entrant(s) to correctly answer the skill question, within 48 hours of notification may result in disqualification”
