Avoid 2 door cars for a family of more than 2 people. If you have kids, intend to have kids in the near future, or drive around friends or family on a regular basis, opt for a 4 door car over a small 2 door car. The process of pushing up a front seat to let your backseat passengers in and out of the car will likely grow tedious over time. Sedans and hatchbacks with 2 doors are good choices with affordable options on the market.
