How should I inspect a used car before I buy it?
user
It depends on what you’re looking for. If you want to buy a car and drive it a lot, then you want to inspect the car for mechanical issues and listen to the car’s engine for any noises that shouldn’t be there.  If you just want to buy a cheap car and sit in it and look at it, you’ll want to give the outside of the car a good inspection to make sure it doesn’t have a lot of dents or other cosmetic issues.  Are you interested in buying a specific car, or just picking up any car for sale?

No, I just wanted to know what to look for in general.

Okay. Well, all you have to do is really pay attention to the car and make sure it’s safe.

Ah, ok.  Hm, I think I might be confused then.  I could explain about how to inspect the car’s engine and listen to it and its exhaust, if that’s what you were asking about?
