Earlier, three such cases of fires were reported and all while the cars were parked.
Sawant collected his brand new Nano from a showroom in Prabhadevi, and headed home at LIC Colony, Mulund (W).
He had spent Rs 2.4 lakh on the silver Nano (MH03 AW 913), which he had got fitted with an A/C and a power steering.
As Sawant cannot drive, the Concorde Motors showroom provided him with a driver to take him home safely.
Just 45 minutes after purchasing, Sawant watched his shiny Nano car transform into carbon black as flames engulfed the car.
"I have no idea what happened. A motorcycle rider overtook me and told me that the vehicle was on fire," said Sawant adding, "The engine was behind me and I did not realise that the car was on fire."
A fire tender rushed to the scene and doused the fire. The Navghar police (Mulund E) have registered a case.
