Although the 2006 Lamborghini Gallardo Spyder comes pretty much loaded, there are several options that have little to do with appearances, including a navigation system ($2,600), an anti-theft alarm ($638), heated mirrors ($173), a trip computer ($460), and a rear-view camera ($2,600). Add a few more little extras, such as leather headliner ($995) and heated, power seats ($3,340) and you will be approaching the average cost of a four-bedroom house in most states. Lamborghini expects the most popular option will be E-gear ($10,000), predicting that 80 percent of buyers will want the electronically-controlled sequential shift transmission.
