The most common complaint about selling a car online is not the offer, it is the smaller number that appears once the truck arrives and the driver starts pointing at dents. Every service below states on its own site that its offer is firm — 'your offer is always guaranteed', 'the number you see in the offer is what we pay', a 'flat-line' offer, or a guaranteed purchase at the quoted value — so the price you accepted is the price on the cheque, not an opening position. That is the whole filter, and it cuts the category hard: buyers whose pages describe a re-inspection on arrival, a valuation that 'may be adjusted at our discretion', or a cheque handed over only after a pickup partner inspects the car are excluded, however good their headline offer. Read each card for what the guarantee assumes, because three of these are junk and damaged-car specialists whose firm offers are typically in the hundreds rather than thousands, and the one general buyer here gates payment on an inspection that can take up to 48 hours before the guaranteed figure is paid.
