What to pay attention to when buying a used car from an automobile dealership

Not everyone can afford to buy a new Nissan car from the automobile dealership. Therefore, there is a high demand for vehicles in the after-market. Not to buy a pig in a poke, many people prefer to ask the specialists of the car service to inspect the used car before buying it. 

And only after making sure that the cost requested for the vehicle is justified, they buy the car. Such an approach helps prevent all the risks and potential expenses associated with fixing a severe car breakage.

In order not to be deceived in such cases, it is necessary to diagnose a used Nissan before paying money for it. This will allow you to identify problem areas of the chassis and engine that are not visible visually, especially for people with no experience. So, what to pay attention to when assessing the condition of a used car?

Level 1 Evaluation: Chassis

The pre-purchase inspection of a used vehicle should begin with a chassis diagnosis. After diagnosing its condition and comparing it with the mileage, the car service specialists can say how smoothly the car was operated. 

In the process of diagnostics, parts with critical wear will be identified, and it will also be determined what types of repair work will have to be performed in the near future. Such diagnostics of a used car provides for the following list of works:

  • Reviewing parts for mechanical damage, matching gaps between paired components, and the lack of the backlash;
  • Reviewing the tightness of shock absorbers by visual inspection for oil drips;
  • Reviewing used cars before buying for the absence of backlash between the steering parts;
  • Reviewing the tightness of the CV joints;
  • Diagnostics of the hub bearings;
  • Reviewing the tightness of the brake hoses.

Only if all the above are performed, inspecting the car before buying will be the most accurate.


Level 2 Evaluation: Engine Diagnostics

Experienced drivers are able to determine by the sound whether a power unit is malfunctioning, but this is not enough to accurately understand its technical condition. In this case, computer diagnostics will help when buying a used car. This pre-purchase inspection of a used car allows you to determine how soon repairs will be required and how much it will cost.

Level 3 Evaluation: Brake and Coolant Inspection

Inspection of a used car before buying does not provide for opening the power unit; you can only evaluate the condition of technical fluids and seals. There should be no engine oil leakage and an incorrect layout of the combustible mixture. It is possible to determine the discrepancy between the fuel and air layout using a gas analyzer. 

In workshop conditions, this piece of equipment determines the oxygen concentration in the exhaust gases. Such an inspection of a used car allows you to find out how synchronously the fuel and air supply systems work, as well as identify problems with the crankshaft sensor or ignition.
