My in-laws are letting me drive and use their 2006 Toyota Sienna minivan. I have been using it as my daily transportation for about a year now. I love this van! To be honest, it is the nicest car I have had. It is particularly useful as I have a 2 year old daughter. When she was younger, the best feature was the automatic doors. I still use them daily to open up the side doors and get her in after picking her up at school or to open the trunk when I am pushing a full grocery cart. It is definitely not a necessity but it sure is a luxury!
Talking about luxury, the seats are all beautiful leather, there is an outside temperature guage and compass, child rear mirror (so you don't have to angle your actual rearview mirror in an unsafe position), pull up window shades for the rear (so you don't have to use the unsafe suctioned shades), 6 CD changer, and sunglass compartment. There is plenty of storage room in the console, plenty of cup and even bottle holders. This is a great car for families with kids---young and old! It would be great on a long road trip.
The only thing I might look for in another car would be actual stow & go seating, but again it is not a necessity. Other luxuries are available as options and are just not on my exact car (e.g. GPS, rear view camera, etc.).
