Lot of 5 A/FX 1970's HO Slot Cars

I DON'T KNOW IF THESE WORK OR NOT as I have no way to test them. The next several lots were bought from the 60's thru recent as the previous owner raced for many years.
This lot includes 5 A/FX HO Slot cars.
The Trans-Am, Vega and Camaro have A/FX on the Grand Am's say made in Singapore. There are two Grans Am Funny Cars , One Black Smokey and The Bandit Trans-Am, One- Chevrolet Camaro Z28 & One Vega Van Gessa
A few blemishes but BODY AND CHASSIS LOOK IN very good SHAPE . With the exception of the chassis on the Red/White grand am think it needs a new one. A COOL LOT, THESE ARE NOT MY EXPERTISE PLEASE REFER TO PICTURES! NO RESERVE!
