There are so many things to consider, and I assume you mean a used car, since the photo is not a new car. Below are the Top 5 Things I would check.
- Has it ever been totaled in a wreck or flood?
- Does it have a clean title?
- How many owners did it have, and in what states?
- What is the condition of the tires and brakes?
- What is the mileage?
