Yes, Runabout is a Japanese company. They don't have a website but they regularly advertise in Road&Ster. They focus more on retro styling and sell things like low-back Cobra seats, the popular Runabout M2 replica mirrors, leather interior accessories, etc. I don't know what the fuel lid is made of because I've never seen one in person but they aren't all that rare. I'd say it's worth about $75-$100 in good to excellent condition.
the fuel lid and the bumper i haven't seen before. the chrome windshield surround i've seen a pic of on this forum on a red car in nevada - the only one i've seen prior to the one on this black car. the wheels are probably black racing or rs watanabe.
most likely this car's been converted from a right hand drive to a left hand drive to comply with philippine road regulations. i can't tell from the pics but hopefully it was done properly.
despite the fact that it's an automatic, the unique pieces seem to suggest that a prior owner was enthusiastic enough to get the car some special accessories.
