According to the Developers of Metropolis Street Racer, to record the audio for the cars, they rented a Mercedes SLK. They tested the car on a test track with microphones attached to the car, recording the sound of each gear until, unexpectedly, the engine blew.

They had to tow the car to a country lane where they could call the AA. They fixed the engine and returned the car but unfortunately, the hire company saw the SLK's engine management report and billed Sega thousands for a replacement engine.
