I went to GMI with a young man named Kris Heberling.

His dad was George Heberling who, at one time, was the Assistant Staff Engineer of the engineering/assembly liaison group for the St Louis plant.

He drove one of the ZL1 Corvettes as his assigned company owned vehicle.

Did he possibly drive the yellow car, which was retailed through Hechler? My understanding is the car was originally an engineer's demo and then was released for sale. I seem to remember seeing a Chevrolet memo asking if any dealers were interested in the car, highlighting this as well.

What about the white Dontov convert used at the testing grounds with another dark ZL1???

Mocked up hot rods, test mules, for the press corps. Built under the eye of GM engineer Gib Hufstader for the long-lead press preview. Long ago crushed/dismantled.

The blue car is a hearsay unicorn and shouldn't be included in the discussion of these three other cars.

Why is that? Was it the late Larry Clain RIP that said there was a Blue 69 ZL1 that he saw NEW with the window sticker in the spring of 69? Was in the 69 ZL1 Vette thread.

----Sadly, we can't dig into Larry's statements. One thing I'm sure of is that at the very least, he thought he saw what he saw. I didn't know Larry (wish I had!) but he seemed a very principled guy. Unfortunately, there are way too few ways to verify his statements, so it seems prudent to not put too much stock in his thoughts on the current situation with a blue car, with 2 or 3 or whatever number of ZL1 Corvettes were 'RPO delivered" 69 ZL1 Corvettes. It's a very confusing situation at this time because there are 3 (at the moment) cars purported to be ZL1 Corvettes and seemingly only two RPO ZL1's. We will see what comes out of this auction of an absolutely cool Monaco Orange ZL1 Corvette.....Bill S

larry was a real deal guy. i bought the ZL1 engine out of the blue car after it was destroyed in an accident.

Does it have a vin on it?

So the ZL1 Corvette bookends are 12/68 - 9/69 with no possibility of any others built in between?
