So let's say we have a hero and a heroine. The hero doesn't own a time machine, but the heroine does and she built her time machine from a modified 1990s era Japanese sports car.
Time travel requires the traveller and the machine to be moving at a certain speed to account for the daily rotation of the Earth (conservation of energy keeps most time machines, including the heroine's time machine, Earth-bound) and works by opening a short-lived wormhole which the machine passes through to the destination time.
Less advanced time machines arrive at the same location on Earth, but the heroine's is fitted with a device that can alter the spatial destination to arrive in a different spatial location. Jumps are limited to a century before our time but have no forward limit.
So why would she build her time machine out of such a car?
