I want to learn about cars, where do I start?

Most of my friends are now talking about different types of cars and I hardly know anything about cars. I only know certain companies that make them like Toyota and Honda. I don't want to be left out being the only one who don't know anything about cars, how can I learn more about cars. What do I do first, where do I start?

Walmart

If there were only some device or medium where a person could literally type in anything they wanted to know about and instantly be able to read everything the world had to offer on the subject… I wonder…

Do some research

You could ask your sister.
