Dealers do not charge more for the same car. The cheapest 'private' sellers are not private.

Everyone buying a used car in Doha has been told the same two things. Buy from a private owner, because a dealer has to make a margin. And if you do go to a dealer, expect to pay for the privilege. We checked both against the 12,444 used cars listed on BuMotar today. The first is wrong, and the second has the wrong villain.

The headline number: no difference

Comparing dealer prices with private prices across the whole market tells you nothing, because the two sell different cars. The median used car from a dealer is a 2021 asking QAR 85,000. The median from a private seller is a 2017 asking QAR 49,000. So we compared like with like: the same make, model and model year, in the same mileage band (under 50,000 km, 50,000 to 100,000, 100,000 to 200,000, over 200,000), wherever at least four dealers and four private owners were selling one.

That gives 70 matched groups and 1,706 cars. In the middle group, the private owner asks exactly what the dealer asks: a ratio of 1.000. Private owners ask more in 33 groups, dealers ask more in another 33, and four are a dead heat. Half of all the groups fall between private owners asking 5.7% less and 7.9% more. There is no dealer premium to be found.

Match the car and the mileage, and a one-car owner in Qatar asks exactly what a dealer asks. The middle ratio is 1.000.

Without matching mileage, one-car owners actually look 1.6% dearer than dealers, across 76 model-year groups. Most of that gap is mileage. Their cars are a little less driven, by about 4% at the median, and on some models by much more. A 2023 Land Cruiser from a one-car owner has a median 52,350 km on it. From a dealer it has 100,000 km.

Who 'private' actually is

That one-car qualifier matters, because the private label on a listing is whatever the seller picked. Of 6,370 used cars listed as private, 1,498 come from phone numbers with four or more cars on the site at once. One number has 76. Somebody selling 76 cars is a business, whatever the listing says. The photograph above this article is a car filed as a private sale, carrying a dealership's plate.

So we split the private listings in two. One group is genuine one-car sellers: numbers with a single car listed, 3,961 cars. The other is sellers with four or more cars listed under the private label, whom we will call traders. The two behave differently:

• Traders against dealers — On the same model, year and mileage band, traders ask a median 2.3% less than dealers. They ask more in only 14 of 51 groups (1,466 cars).
• Traders against one-car owners — One-car owners ask a median 5.9% more than traders, and more in 22 of 32 groups (535 cars).
• What traders list — Newer cars than the other private sellers: a median 2020 model at QAR 87,000, against a 2016 at QAR 40,000 for one-car owners. Only 13% of trader listings name a trim, against 27% of one-car owners and 49% of dealers.

Where a matched group has enough of all three kinds of seller to compare, 31 of them, the trader has the lowest median ask in 15. Dealers are lowest in six and one-car owners in five. The cheapest price is most often a trader's: someone with a lot of cars to move who lists like an individual. That is not necessarily a bad car or a bad deal. But it is not the deal people think they are getting when they go private to cut out the middleman. The middleman is the one selling.

What the Land Cruiser rows look like

The Land Cruiser is the one car with enough sellers of every kind to show the pattern year by year. Here are median asking prices from dealers, one-car owners and traders, by model year:

• 2024 — Dealers QAR 230,000 (97 cars), owners QAR 236,500 (16), traders QAR 229,000 (21).
• 2021 — Dealers QAR 165,000 (67), owners QAR 168,500 (14), traders QAR 159,000 (15).
• 2018 — Dealers QAR 130,000 (33), owners QAR 144,000 (10), traders QAR 119,000 (9).
• 2016 — Dealers QAR 109,000 (42), owners QAR 110,000 (22), traders QAR 103,500 (16).
• 2013 — Dealers QAR 69,000 (46), owners QAR 66,500 (10), traders QAR 61,500 (14).

These rows do not control for mileage, and it shows in places. The 2018 owners' cars have about 18,000 km less on them than the dealers'. The traders' 2013s have about 58,000 km less and still ask the least. Across all models, the matched comparison is the one to trust.

There is one thing dealers do that one-car owners often skip: stating the mileage. Every used dealer listing on the site gives it. One in ten listings from one-car owners does not. A missing odometer reading is not an accident often enough to ignore.

What to do with this

• If you are buying — Do not rule out a dealer on price, because on the same car the asking price is no higher. What a dealer can give you that an owner cannot is somewhere to go back to. Ask what warranty, inspection or return terms come with the car, and get them in writing. If the cheapest listing is a 'private' seller, ask how many cars they are selling. The answer changes what you can expect after the sale.
• If you are selling one car — Your competition is a dealer at about your price and a trader about 6% under it. Price for the trader, not the dealer. And state the mileage: listings without it are the ones buyers learn to skip.
• If you are holding — Nothing here changes what your car is worth. It changes who sets the floor when you come to sell, and in most rows that is a trader.

What we do not know, and what would change the answer. These are asking prices, not sale prices. Dealers may hold firmer or discount harder at the end, and these listings cannot show which. "Trader" here means a phone number with four or more live listings under the private label. That catches families selling two cars at once only rarely, and it misses traders who rotate numbers. The model field does not reliably separate trims, so some rows still mix a GXR with a VXR. Mileage bands are wide: a car at 51,000 km and one at 99,000 km sit in the same band. And none of this measures condition, service history or accident records, which are what a dealer's warranty, where there is one, is meant to cover.
