Buyers are often put off purchasing convertibles because of their inherent disadvantages. Among them: noise, cowl shake, potential water leakage and increased risk of theft by break-in. Manufacturers of expensive luxury roadsters have overcome these problems with high-tech folding metal roofs. Now, manufacturers are beginning to develop more affordable systems for the rest of us. The newest and example of an affordable hardtop convertible is the all-new 2007 Volkswagen Eos.The Eos, named after the mythical Greek goddess of dawn, delivers the top-down thrill of driving on a sunny day and, at the flick of a button, the warm, quiet comfort one desires on a cold or wet day. When driving with the top up, the Eos feels tight and quiet, like a coupe. With the top down, it feels more like a convertible but tighter, with less cowl shake on rough roads, than in older convertibles. The glass top gives the Eos a unique appearance, and it's entertaining to watch when raised or lowered, a feat that can be performed by remote control. In spite of its diminutive dimensions, the Eos seats four, and getting into the back seat is relatively easy. The interior is trimmed nicely, an area where Volkswagen excels.
