Luxury sedans from Lincoln, Infiniti, Acura and Cadillac fared poorly in the latest bumper crash tests by the insurance industry, sustaining more than $US1,000 average damage when hit at five miles per hour, the Associated Press (AP) reported. Two 2003 sport utility vehicles -- the Mitsubishi Outlander and the Volvo XC90 -- also were rated "poor" in bumper crash tests, AP said, citing the US Insurance Institute for Highway Safety. The 2003 Honda Element SUV was the only vehicle of the seven tested that rated "acceptable," sustaining average damage of $537 in the four tests performed.
