Great question and tough to answer given that good seating position for short people has little to do with the size of the car. Airbags are a particular concern. The National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety consider 10 inches to be a safe distance from the air bag. If you're sitting closer than ten inches to your car's airbag, you should have an on-off switch installed. Alternatively, you can have pedal extenders installed on your vehicle. Other concerns include the ability to reach controls, visibility and seat belt positioning and comfort. Edmunds.com has addressed this issue rather well. Here is an excerpt that should help guide you. Good Luck!
1. Scion xA: Although it offers few frills on the inside, a tall cabin design and great sightlines make this inexpensive five-door hatchback worth a look.
2. Mazda 3: Available as a sedan or five-door hatchback, the Mazda 3 offers good visibility and a standard tilt/telescoping steering wheel. Upgrade to the higher-line "s" model and you'll get a height-adjustable driver seat.
3. Volkswagen Golf, GTI and Jetta: Built on the same platform, these VWs are easy to see out of and almost anyone can find a comfortable driving position in them. Seat-height adjustment and a tilt/telescoping steering wheel are standard.
4. Mini Cooper: We've never been wild about its funky manual seat adjusters, but there's no denying that the pint-sized Cooper's cockpit is well proportioned for smaller drivers. A height-adjustable driver seat is standard, and visibility doesn't get much better than this.
5. Subaru Forester: If you really want an SUV, the Forester is just about the perfect size — it's tall enough to give you a nice view of the road but not so tall that you'll have difficulty getting in and out. A height-adjustable driver seat is standard. Around back, the Forester's liftgate is lightweight and a sturdy grab handle makes it easy to close.
6. Chevrolet Malibu and Malibu Maxx: Although roomy enough to accommodate people of all sizes, this sedan and wagon team is a good bet for shorter drivers — adjustable pedals and a tilt/telescoping steering wheel are optional on all models.
7. Honda Accord: The current generation of this well-rounded family car goes a long way toward keeping its occupants happy. Visibility is excellent in the sedan, thanks to a relatively low cowl. Besides that, seat-height adjustment and a tilt/telescoping steering wheel are standard from the LX model on up.
8. Volkswagen Passat: This premium family sedan has a cozier cockpit than the Accord or Malibu and features an exceptionally wide range of both seat-height adjustment and telescoping-wheel adjustment.
9. Toyota Sienna: The Sienna isn't the only minivan that offers a good view of the road, but it's the only one that comes standard with a telescoping steering wheel.
10. BMW 3 Series: Got a little more to spend on a car that fits you just right? Well, it would be hard to go wrong with the 3 Series. The sight lines are good, the seats are supportive and there's a multitude of ways to adjust both the seats and steering wheel.
