How many cars have articulating wings? and what do the cars cost? The Crossfire N/A might be the lowest priced car with one. I like raising it up when there are good looking chicks in the car behind me. They usually smile and wave. LOL

 

Paul if we're talking "window sticker" price, I think that honor belongs to the Turbo Beetle.
Vpats, I think the most important benefit of having the spoiler (on a car with a fastback roofline like ours) is to disrupt the air flow passing over the car to prevent lift, at autobahn speeds.
The makers of the Audi TT found out the hard way.
