Also part of the premium audio package is Sirius Satellite radio, which can be programmed using the in-dash LCD screen.

With the roof up, the A4 Cabriolet's variable cargo bay can be increased in size, for those trips to the shopping mall.

We were impressed with nearly every aspect of the Audi's Bluetooth interface. The system copies over a cell phone's address book and call records, including recently made calls, missed calls, and outgoing calls.

As we found in our review of the 2007 A4 sedan, entering destinations using the alphabetized rotary dial is simple, but time-consuming.

To program destinations into the navigation system, drivers must use a simplified, stack-mounted version of Audi's MMI interface. This system is due to be replaced on the 2008 A4 with a full, central console-mounted system, such as that on the 2007 Audi A6.

With the navigation system installed, the as-standard six-disc changer moves over to the glove box, and, curiously, loses the ability to read MP3 discs. Digital-age audiophiles can opt for an iPod connection instead of the CD changer.

Considering it had the smaller of the model's two engine options, our 2-liter A4 Cabriolet tester was still an impressive performer. It may take all of 7.9 seconds to get to 60mph (half a second slower than the heavier A4 sedan) but in city driving, the direct-injection, turbocharged A4 Cabriolet feels responsive and light on its feet.

The peppy A4 Cabriolet 2.0T Quattro will appeal to those looking for a stylish, sporty ride with an element of real-world functionality, thanks to its relatively good gas mileage, comfortable cabin, and impressive storage facilities.

Those who option up the $1,000 premium audio package get a Bose-branded Sirius Satellite radio, which can be programmed using the in-dash LCD screen.
