Toyota dealers interviewed by The Japan Times voiced relief Wednesday over the result of a 10-month investigation by NASA and the U.S. Transportation Department clearing the automaker's electronic throttle systems, saying they never lost confidence in the safety of the cars they are selling.

"Honestly speaking, the U.S. has finally understood . . . (Toyota cars) did not really have any problems," said a 30-year-old Toyota dealer in Tokyo who spoke on condition of anonymity.

Although the scandal over unintended sudden acceleration in Toyota vehicles has damaged the carmaker's reputation, he said the latest announcement will help the firm regain public trust and he will be able to sell Toyota cars with confidence.
