I've had both and Love my M's.... 07 M35 and 08 M45S! Both ADV. TECH(a must). Can't say enough south these cars. Regular package will have wood grain dash and door panels. 18" wheels, softer ride, Sport will have carbon fiber dash and door panels... Aluminum trim, 19" wheels, rear active stear, no Tan leather option [usually graphite (black) or stone(grey)], most wheel have body lip kit (ground effects).
Both GREAT choices but most of us like the details on the Sport! Good luck on your search and remember... ADVANCE TECHNOLOGY package! 14 spkr Bose sound system, DVD, ICC Intelligent Cruise, LDW lane departure warning system, AFS adaptive front lighting system.... Above all the other great things these cats come with. Dealers and people tend to advertise FULLY LOADED but make sure it actually is!!
