Buying a used car is a smart investment when done right; done wrong, it opens the door to months of expense and regret. A car's exterior may look spotless and its advert may say "flawless"; but its true condition only emerges from a systematic inspection. A pre-purchase inspection means examining the car technically with an independent eye before you buy. The aim is not just to find faults and negotiate; the real aim is to see hidden problems that will cost a lot later, and to make an informed decision. In this guide we cover, under main headings, what should be checked on a used car.
What most reveals whether a car has had a serious accident in the past is the paint and body. Paint thickness is measured panel by panel with a gauge; values clearly different from the original factory paint show that panel was painted or replaced. Watch for these:
The engine is the car's most expensive part and hidden problems should be sought here most of all. Abnormal noise, shaking or hard starting on a cold start; thick blue (burning oil) or white (coolant) smoke from the exhaust are warnings. Oil-antifreeze leaks on the engine block and gaskets, and sediment in the radiator, are checked. The oil level and colour show whether the engine has been maintained. With a diagnostic device, the engine control unit's memory is read; past and current fault records and cleared error codes emerge here. This is the most effective way to catch electronic problems invisible to the eye.
On manual cars, the clutch bite point and whether the gears engage cleanly are tested; on automatics, whether the gear changes are smooth. On a road test, late or harsh gear changes, a slipping feeling on take-off, or abnormal noise can be signs of a gearbox problem. Gearbox repair is one of the costliest jobs; that is why it must be assessed before purchase. If the clutch is worn, the bite point escaping at high revs can be felt.
The brake pads and discs, brake balance and handbrake hold are checked. Shock absorber leaks and play in the control arms and ball joints are examined with the car raised. Uneven tyre wear points to an alignment/balance or suspension problem, and whether all four tyres are the same brand/age matters. In a hot climate like Adana, the ageing of tyres and hardening of the rubber should also be assessed.
The lights, indicators, windows, central locking, screen and sensors are tried one by one. The air conditioning and heater operation and the sufficiency of the gas are checked; in hot Adana conditions the air conditioning matters greatly and is an expensive repair item. The battery and charging system are measured. The genuineness of the mileage is assessed by cross-checking the maintenance history, part wear and electronic records.
What tells you the real condition is not where the seller shows you, but where an independent eye looks. As Temel Servis, we provide pre-purchase inspection and diagnostic service for all makes in Seyhan, Adana; and we specialise in Opel and Chevrolet in particular. Bringing the car you like to us before buying lets you see, in advance, the large expense that could arise later. You can reach us at Fevzipaşa Mah. 48057. Sk.

An inspection largely reveals the problems that can be measured and detected at that moment: paint and body condition, engine and gearbox health, electronic fault records, brakes and suspension. However, it does not guarantee future faults; the aim is to measure risk and enable you to make an informed decision.
A comprehensive pre-purchase inspection is usually completed within one to two hours; the time can vary with the car's condition and the level of detail requested. The road test and diagnostic reading are part of this time.
No. A panel locally painted because of a small scratch or stone chip is usually not a problem. What really matters is whether there is repair on the load-bearing chassis sections, replaced parts or signs of a serious accident. An inspection helps you make this distinction.
There is no single definitive method; but the maintenance history records, the consistency of pedal-steering-seat wear with the mileage, and information in the electronic modules are assessed by cross-checking. Inconsistencies raise suspicion and call for closer examination.
For an impartial assessment, an independent workshop is safer. An inspection with no ties to the seller looks only to your interest. Temel Servis is an independent auto service and carries out the inspection impartially, on your behalf.
