I want to know how to find out about driver's seat space and surrounding the driver's seat... I am a large woman and have bad knees, I am about 5'5 and want my head space... how do I know which vehicle will give me more of each of these... I have looked at Ford Escape, Subaru Forester, Saturn Vue, Mazda Tribute, Ford Camry, PT Cruiser, and currently drive a V6 Plymouth Voyager and AM very comfortable in it, but I am looking for something a bit smaller but the same comfort as my current van... any suggestions from anyone... thank you so much
