smart produced about 43 000 roadsters between 2003 and 2006. Sales were meeting projections but warranty claims due to leakage problems halted production. This one we spotted in Padova, Italy has a removable Targa roof. An electric powered soft-top was another option available. With a six-speed automatic transmission and rear mid-engine, rear-wheel drive layout the roadster's fuel economy is about 45 miles per Imperial gallon.
