The answer should be simple, you buy a new car. But, they are often expensive and many of us cannot afford them.So the answer becomes more complicated. Young people buy used cars much more than older people. Because they don’t have the experience, serious mistakes are possible. For example, you found a certain car online, at a price of just $1.000. You looked the same model (the same year and engine) and their prices are between $1.500 and $2.000. Should you buy it? Of course not, something is wrong with that car.
If you are looking for a cheap BMW, Mercedes or similar, forget it. You must pay attention to some, less known brands. When you finally found the car you are looking, go and look it. Before you start the engine, the check is it hot. Warm engine starts easier than a cold one. Also, look under the hood and under the car. If you find some minor traces of rust and damages, you can even repair them by yourself. But, if you see a lot of rusts, leave that car! The repairs will cost more than the whole car. If everything is fine with bodywork, go for a test drive. Pay attention for any sound and vibration that looks suspicious. In a just one mile, you can test handling, brakes and gearbox. Every part should run smoothly and without making any sound.
When you bought a car, change the oil. Many previous owners will tell you that they already changed the oil, but it is a lie. Beside oil and oil filter, you should replace the air filter as well. Then, you are ready to drive.
