The standard size car is generally a Nissan Altima, VW Jetta or Hyundai Sonata. This is a good compromise between a small car and a full size. Spacious, but not too big, yet comfortably sized. The next size larger from a standard size car is a full size.
Car sizes can be hard to understand. Some companies consider the Nissan Altima to be a full size rather than a standard size car. So choose the car carefully.
When selecting a car note the size vehicle you ordinarily drive. Your family car is a good indicator of the best car to select for your vacation. The family car tends to have the right number of seats, leg room and passenger height requirements. When you factor in luggage you might need more space.
The standard size car is right between the space of a full size and a mid size car. Perhaps it is the most appropriate size for your visit.
