Kids And Adults LOL I have been in and out of Slot Cars since 1967 there just like real cars the older you get the more you spend and the faster they go! I havent Raced since 2002 But The Class I was Racing Was Group 27 and Open Class which will make a lap around a 165 ft Banked (Blue King) track in about 3.5 seconds you need a Flashy paint color on your body when racing to keep your eye on your car verses the other seven cars racing at the same time it is alot of Fun Also got in to Drag Racing Slot Cars on a Drag Strip
