Only these defects qualify, and only if the listing didn't disclose them before the sale.

    A cracked block, a failed crankshaft, or failed connecting rods or rod bearings.

    Slipping, or failing to shift.

    Accident cuts, welds, or rot with holes larger than 1 inch.

    Evidence such as a flood waterline, or mold in electrical modules.

How to make a claim

  1. Email us within 72 hours of delivery

    Write to support@remarketspace.com with the stock number. Email works any day, weekends included; the time we receive it is what counts.

  2. List every problem in that one email

    We take one claim per car.

  3. Send photos or video

    Of the VIN, the odometer and the problem. If the car can't be driven, a video of it running in place is fine.

  4. Send a mechanic's report if we ask

    From an ASE-certified mechanic; a mobile mechanic counts.

  5. Keep the car as it arrived

    No repairs, and no more than 100 miles.

The guarantee applies to cars paid in full within 48 hours of winning.

What happens next

A problem with the car doesn't qualify by itself: it has to be one of the covered defects above, undisclosed, and the claim has to meet the rules above. We review every claim and answer in writing.

You keep the car, and we refund 25% of your winning bid, up to $500.

Winning bid

Transport costs aren't covered: a car that comes back is returned at your cost.

Questions

Is this a warranty?

No. Every vehicle is sold as-is, under our arbitration plan. The 3-Day Major Mechanical Guarantee is the part of that plan that covers the major problems on this page when the listing didn't disclose them.

When do the 72 hours start?

When the vehicle is delivered to you. The 72 hours are clock hours, weekends included, and you can email us any day. The time we receive your email is what counts.

What if the car can't be driven to a shop?

If we ask for a report from an ASE-certified mechanic, a mobile mechanic counts.

Which vehicles have the guarantee?

Cars, SUVs, vans and pickups that started at the auction. Buses, commercial or heavy-duty trucks, boats, RVs, motorcycles, powersports, snowmobiles, trailers and equipment don't have it. The listing shows the guarantee when the vehicle has it.

What about title or mileage problems?

They aren't part of this guarantee. Title and mileage issues have their own, separate coverage. Email support@remarketspace.com and we'll explain how it applies to your car.

Who pays to send a car back?

You do. Transport costs aren't covered, so when a car comes back, you return it to us at your own cost.
