Buying a used car from a dealer in Spain: the oil roulette in Madrid

Buying a used car from a dealer in Spain: the oil roulette in Madrid

Buying a second-hand car from a professional dealer seems safer than buying from a private seller, but a recent case in Madrid shows that legal warranties do not always protect the buyer. A user bought a vehicle two months ago and within a month noticed that the oil level dropped from maximum to minimum in less than 400 kilometres. The dealer has no workshop of its own and referred the problem to a garage that refused to carry out the repair; the brand's official dealer also refused to issue a quote for the claim.

The ordeal of the inspection and the legal warranty

Spain's Consumer Goods Warranty Law (Ley de Garantías) establishes that the professional seller is liable for defects for six months. But in practice, proving a defect such as abnormal oil consumption requires a rigorous expert report: sealing the filler cap and drain plug, measuring against the manufacturer's tolerances (which may allow up to one litre per 1,000 km), and opening the engine to determine the cause. The cost of the inspection and the lawyer can exceed 2,000 euros, an amount only worthwhile if the car is worth more than 10,000-15,000 euros. For a 3,500-euro vehicle, the economics simply do not add up.

The risk of the dealer becoming insolvent

Another added difficulty: by the time the case reaches a verdict, the dealer may have disappeared or become insolvent. This risk is real in a sector where many companies operate on minimal resources and change their company name frequently. That is why some users recommend going directly to official dealerships of brands with a good fruta (Toyota is cited as reliable) or, better still, buying from a family member or acquaintance whose treatment of the car is known.

Specialised law firms and out-of-court solutions

Companies such as Lexmecánica or We dot offer combined inspection and legal advisory services, but there are no clear references about their effectiveness. The fastest route is the threat of a lawsuit and an out-of-court settlement with the seller. However, without a solid expert report, the dealer will hardly back down. The final message is clear: before buying a used car from a professional, invest in an independent inspection; after the purchase, the legal route is long, expensive and with an uncertain outcome.
