we have 3 cars & 3 drivers.
DH commutes with the Honda Insight. His commute is to Chelmsford, MA a minimum of 1-1/2 hrs from our home in NH. so at about 75 + MPG the Insight is a must for him
I drive a Honda Accord, work seasonally, but very different hrs than DS or DH; & DS17 has an Olds Achieva (poor thing, not a real babe magnet!

) DS17 drives himself to work--which is different hrs totally from DH's hrs. He is homeschooled so no driving to school
I feel we could get along with 2 cars. We did go with only one car when DS was an infant & toddler, it was doable, but a pain. since both of my parents were kids during the Great Depression & DH's parents were also frugal, we've both grown up with the 'you don't make wasted trips' philosophy
we are in the market for a used pickup--we need it for the business, dump day (no trash collection in the sticks) & for fetching things(for the most part, no appliance delivery out here, either--& when there is it is pricey

)
we will only run the truck for those things &
may give the Honda the heave ho
