Afraid not
I "loaned" my cars to my younger brother when I started work...and he lost/broke/destroyed all of them
They were not true Scalextric cars, more custom built with brass chassis, flexible polycarbonate bodies, sponge tyres for grip and hi-performance motors for running on seriously long 4 lane permanent club circuits which were "the thing" back then.
In fact the cars we used would not run on comercially available tracks, although the cars were 12volt powered the amp draw on the motors melted standard controllers and required a lorry battery on constant trickle charge to power a 4 car race.
All of my hard earned pocket money was swallowed by that hobby, until I discovered that other huge money sponge....................girls
. From then on until the discovery of GPL, I was lost in the wilderness. lol
