To get the most money out of your car sale, check out a few details - from documentation to aesthetics.
As for paperwork, it is necessary that you have on hand the original invoice for the car, a valid handling certificate, the last 5 inspections, and holdings, current insurance (can be assigned or canceled), advice on fines, a document on non-presentation of theft and, if possible, records of his service.
If you need any of these documents, it may affect the amount you ask for the car, as the buyer has the “right” to negotiate a lower price as he will have to bear these costs.
As for the exterior, spend one weekend thoroughly cleaning the windows, tires, rims, plates, and the body in general. It only requires your patience and minimal investment.
The engine is another important part that needs business plan to look good when you open the hood, so take it to a trusted mechanic or the brand's workshop so they have everything they can clean without damaging electrical or mechanical components.
A good option is to entrust this to a specialist in car cleaning, repair, and detailing, but it will undoubtedly be a little more expensive. However, these costs can be reimbursed when the vehicle is sold.
