In addition to traditional optional features like a navigation system, power moonroof and Sirius Satellite Radio, buyers who want to customize the C30 can do so through Volvo's Custom Build program. Custom Build features include bi-xenon headlights, BLIS, cruise control, special trim pieces and aluminum pedals. There are also more exterior and interior color combinations offered with the program. In addition to the cost of any options, there is an additional $300 fee for using the Custom Build program.
