You are looking at a very neat vintage radio controlled Tyco (aka "Taiyo") Porsche 959 R/C car. Although it does not include the original radio controller, the car itself is in good condition and has not been stored with batteries installed. All parts articulate smoothly. It is reportedly compatible with any 49Mhz transmitter, but it could also be a nice display piece for a Posche, R/C or scale model car collector.
This item was made in Singapore and is an excellent example of a detailed 1980s officially licensed R/C racer with high quality decals and paint. Measuring roughly 8" long, it presents well from all angles.
