Eternal dispute between buyers on Avito

In my repair practice, two opposite situations regularly occur:

• Scenario A:The buyer brings a carcass with a perfect glossy body without a single scratch. He says: “I bought it like new!” Checking EXIF ​​- 280,000 frames in the studio on a tripod! Shutter on last breathing.
• Scenario B:The camera has worn corners and a loose elastic band on the grip. Checking EXIF - mileage only 18,000 frames! The owner simply carried it without a cover in his backpack.

What does the service center technician say?

Scuffs on the case and peeling rubber bands are **cosmetic defects** that can be repaired for 1,000 rubles by purchasing a new set of rubber bands on AliExpress. But a bolt block that is 95% exhausted is a **critical mechanical fatigue**, threatening repairs costing 20,000 rubles.

Risk comparison table

Camera sign	What does it really mean	Criticality for purchase
Scuffs on the corners of the metal case	Friction from a bag or belt. Does not affect mechanics.	Low (Great turn for bargaining!)
Ideal body + Mileage > 150k	Studio work from a tripod. The shutter mechanism is worn out.	High
Dents and chips from falls	Shock loads. Risk of board cracks and matrix displacement.	Critical (Don't take it!)
