A few months back we attended a driving event in San Diego. For the return trip to Orange County, GM loaned us a 2007 Saturn Aura XR for a week of evaluation. Since our tester didn’t include a window sticker, we had to do some calculating to figure out the price. We came up with $28,019, which is based on the XR’s $24,345 base price, a $650 destination charge, and optional features such as XM satellite radio ($199); an Enhanced Convenience Package with power pedals and a power passenger seat ($425); premium floor mats ($100); leather upholstery and trim with heated seats ($800); and a full-length sunroof ($1,500).
