Otherwise known as used parts audi auto delovi beograd , these have come off scrapped cars. They’re the cheapest parts of the lot but unless you’re driving an old banger, you shouldn’t consider them. You don’t know how many miles they’ve covered or what condition they were in when they were taken off the donor car. And you don’t know how they’ve been stored. Very few salvage yards keep car parts somewhere that’s completely watertight, no matter how delicate they are.
