New & improved Grey Ghost (PICS)
We have a test area here in Cumberland also. We regularly see cars all taped up being tested for NVH. And for long term testing by GM. We had a solstice here for many months before they came out. Im keeping my eyes peeled for an HHR in disguise. I'll let you know if I find one.
Hmmm, not aware of any GM engineering test tracks in MD. Oh, that might be a manufacturing track (since you mentioned the Solstice). The build plant, in Deleware, is probably near there.
