Best car - the one I drive now, a Subaru Outback. It's just like the one in the com mercials - full of huskies!
the worst was an ancient orange station wagon. It was falling apart. The driver's side door didn't work, and I was pregnant, what a pain! Some guy my then-husband worked with told him he should be ashamed of himself for not taking better care of his family-- it worked, he got another car. (Not married to him anymore.)
