Introduction
As a sector professional, you know that every car you buy is an investment. Buying badly can translate into losses, claims or dead stock. Buying well, on the other hand, means margin, turnover and satisfied customers.
In this article we give you a clear, actionable list of everything you should check before closing a purchase. Ideal whether you buy from private sellers, at auctions, from wholesalers or through leasing.
1. Basic mechanical checks
Before buying, always check:
Engine condition: Cold start, unusual noises, smoke.
Gearbox and clutch: Road test and smooth transitions.
Brakes and suspension: Response, uneven tyre wear.
Lights and electronics: Everything should work, including electric windows, air conditioning, sensors.
Valid or expired MOT: If it will not pass, calculate the cost and risk.
Dealcar tip: If you buy without seeing the car, request an external mechanical inspection or require it from the supplier.
2. Legal and document checks
Always check before signing:
Registration certificate and technical data sheet.
Actual ownership: Check that the seller is the owner or has authorisation.
Outstanding finance or seizures: Request a Traffic Department (DGT) report or use tools such as Carfax or Autofact.
Transfer tax (ITP) or invoice with VAT/REBU: Depending on the source, verify the applicable tax regime.
Accident or claim history.
Dealcar tip: Use platforms that connect with the DGT to check everything in seconds and avoid surprises.
3. Commercial value and resale potential
Ask yourself these questions before paying:
Is it being sold below market value? Why?
Is there demand for that model in your area or on marketplaces?
Can you offer a warranty without risk?
Does the cosmetic condition allow you to sell without investing much?
Dealcar tip: Check marketplaces such as Coches.net or AutoScout24 to see the real average selling price, not just the advertised one.
4. Hidden costs and after-sales
Calculating the real margin means adding:
Purchase price + transport + cleaning + repairs.
Paperwork (change of ownership, fees, agency costs).
Legal or commercial warranty.
Advertising or listings.
Dealcar tip: Use a spreadsheet or tool that calculates your net margin before you decide.
5. Documentation ready for sale
Avoid later delays by checking:
That the car has a spare key set.
Manuals, service book or digital history.
Environmental badge, where applicable.
Dealcar tip: Everything you have in order when buying will save you calls, costs and time when selling.
Conclusion: buy with method = sell with margin
It is not about luck or intuition. The dealers who achieve the best margins follow a clear method: check, calculate and decide. The more systematic you are, the fewer unexpected issues and the better turnover you will have.
