what car should i get for my first car, i was thinking to get a second hand car but i have no idea what to choose.?

You said you want small. The reason insurance is high on certain vehicles is because some are high performance. For example a Corvette will have very high insurance as opposed to a Ford Explorer. Get what you like and afford. Talk to an insurance agent and tell them the cars you like and they can help you narrow down your choices.

Mazda 3

Think of dependability and affordability. Personally, I would look at older Chevy and Toyota for gas mileage and stay clear of the turbo's which break down and cost a fortune to fix.

Here is a good article to help you make your choice.

Visit a few used car lots then look around, really. See what cars you like, see the prices too.

It also all depends on your price range and do you want a coupe, sedan, or suv, etc.......
