OK, so the thread is revived, but it's still fun.
Vehicles to pick on the most are convertibles. The one that just puts a "what were they thinking" look on my face is the Nissan Murano "CrossCabriolet"...
I would rather have a Mercury Capri, Chevy Cavalier Z24 Convertible, or Geo Metro Convertible (granted, the Chrysler Sebring was the standard for many years, as was the LeBaron before it). Don't get me started on a PT Cruiser Convo -- I actually had to rent one once (in the dead of Winter) and I'd rather not talk about it).
EDIT: So I almost forgot about the Dodge Dakota Drop-top. I would almost give it kudos for being functional, fun, and El Camino-like in the same sentence.
