Learned something, too. I didn't know there was a surviving '83 around.
I knew of that one, but after reading some other sutff lately, there actually maybe more. The made 45 originally, but due to new California emissions, they didn't meet regs so they were supposed to be all dis-mantled. The emloyees of the plant took this one and kept hiding it around plant until the okay was given to start production in 84. Supposedly all were dismantled except this one, but rumors are a GM official owns one and there are a handful of '84 models that were built in early 83. So these cars may have been put in storage and then new VIN's made to make them '84 models.
Its sad lets hope the cars can be fixed...
Maybe the 3 you can see can be repaired, but I doubt the ones underneath the rock pile will be salvageable.
