Well, that's a subject I've been looking for. Some people buy cars without knowing what they actually need to know about cars. And usually, it's just basic information, but it can make a great change. I faced some problems when I bought my first car... I didn't know much about it, I just paid someone to check if everything was in good condition, and got a Golf 6 with 8k, but after half a year, the car's engine broke down and I had to pay 2,5k for a new one. And month by month, a lot of other problems appeared and I got to the conclusion that I should've been more informed before buying it. So make sure to be informed, learn about how to compare prices, or car costs per mile, or anything like this. It will be very helpful.
