Toyota Prius: perfect for young adults without infants.
2010 Toyota Prius II
I love the fuel efficiency and size of my vehicle, but I do not think it would be large enough if I had any small children. Fitting a car seat of any size in the backseat can be difficult. I have had issues in the past with there being a recall or a technical issue with the vehicle. This can cause the vehicle to shut down while driving -- the power will shut off, you cannot accelerate or shift gears, and powering it back on is nearly impossible. This can be quite dangerous when driving on an incline or the interstate and the vehicle decides to shut down. But again, this only tends to happen when there is some sort of recall or technical issue. On a daily basis, the vehicle is able to withstand an hour-long commute and gets excellent gas mileage.
