TOP 5 checks before selling your car: how not to lose value
Car preparation before sale: diagnostic, servicing, brake inspection and bodywork to increase resale value.
Selling your car is not just about placing an ad – the right pre-sale preparation can increase the resale price by hundreds or even thousands of euros. At Mario Garage in Cagnes-sur-Mer, we know exactly which technical and cosmetic details influence a buyer’s decision the most.
Complete vehicle diagnostic
Before listing your car, it’s essential to perform a pre-sale diagnostic:
Engine and electronic system check
Suspension and shock absorber inspection
Gearbox condition review
Why? A buyer will immediately notice issues during the test drive. Fixing small problems before selling usually costs less than losing €500–1000 during negotiations.
2. Oil change and filters
One of the most common buyer questions: “When was the last service done?”
Oil change with high-quality brands (Motul, Castrol, Mobil)
Replacement of oil and air filters
Cabin filter check
Why? Fresh oil and filters show that the car has been regularly maintained, boosting buyer confidence.
3. Brake system inspection
Brakes are a key safety and value factor.
Check of brake pads and discs
Inspection of calipers and hydraulic hoses
Why? Unusual noises or long braking distance will immediately reduce the selling price.
4. Bodywork and appearance
A clean, shiny car always sells faster.
Small dent and scratch repairs
Professional car polishing and headlight restoration
Interior detailing and deep cleaning
Why? First impressions count – a well-maintained exterior makes your car look newer and worth more.
5. Documentation and history
Prepare all invoices and service records
Show maintenance and repair history
Why? Transparency builds trust. A clear history helps avoid doubts and limits aggressive price negotiations.
