In the scene where Aki is rescuing James Bond in her white Toyota 2000GT roadster from Ernst Stavro Blofeld's men in front of his hotel, there is a scene where Bond and Aki are looking over their shoulders at the bad guys pursuing them while their car is speeding down the road.
If you notice, the tachometer on the dashboard in front of Aki is setting on zero. Maybe the faulty tach is covered under warranty?
