This pertains to an obscure childhood memory that keeps coming back to haunt me every now and then. And it's been kinda bothering me again the last couple days....
I remember going with my Dad somewhere when I was a little kid to take the car in for repairs. Can't even remember where the shop was at or what the name of it was, but what I DO remember was this thing on the counter that I believe was supposed to demonstrate the advantages of good shock abosrbers. It had two toy cars on it that sat upon a rubber strech of "road", and there was a crank on the side. When the crank was turned, the cars appeared to be travelling on the road which also happened to be littered with bumps and potholes. I believe the cars were something along the lines of mid-60's Buick Rivieras or Olds Toronados (Kinda like dealer promotional models, only with full-floating suspensions that acually WORKED!).
Anyone here have any idea what I'm talking about? It's probably been thirty years since I've seen one of these things. Closest thing I can compare it to today would be those Lucas Oil demonstrators with the gears that seem to adorn the counter of every auto parts store in the nation. I wouldn't mind acquiring one of these contraptions either...that is as long as I wouldn't have to pay out the wazoo for one!
BTW: I tried doing a search on eBay a couple times under "shock demonstrator" or "shock absorber demonstrator" and came up with nothing.
