Which one should i get?

Never, Never, Never buy a car on Craigslist unless as everyone mentioned it was a classic! Got to a used Car dealership! And dealerships do have cars in the 5-6k price range. Or check your local newspaper listings. If its local, you can at least see the car in person and talk to the owners. And check with local service shops, sometimes they’ll offer a free inspection on the vehicle you’re looking to buy.
