Has it occurred to you that the cars at shows are normally the exception from the norm?

Those cars at shows are more often than not seen as special by someone, and saved from the ravages of daily use, then subsiquently scrapped.

How often have you seen a bone stock Chevette at a car show - NO, not a hot rodded one... but a boring old regular one, like what were seen everywhere around the time you bought your dad's Formula!?

The "common" cars are driven till deemed unreliable, then tossed out.

How often do you see Lemans or Chevelle wagons, let alone four door cars with rubber floor mats and vinyl bench seats.

When I bought my first Grand Am, the front wheel drive ones built between 1985 & 1991 were EVERYWHERE, now they are no where to be seen... and this wasn't even twenty years ago.
Now the few 85-91 Grand Am's that pop up from time to time are either Quad4HO cars, or 2.0L Turbo cars - and normally the top of the line "SE" models, not the base or "LE" models.
How about the other GM N-bodies, like the Oldsmobile Calais or Buick Skylark(?);
Odds are the only ones you will ever see from here on in, will be the Calais Quad442... and even those were not built in high numbers.
