That's really strange. The car lots I drive past are lower than usual in inventory, but not like that. I'm talking all brands - not just one. Now granted, I am also not looking every day but this past week there were plenty of cars on the Chevy dealerships lot here. Were they all new cars - I don't know. But the lot wasn't empty either.I had a pleasant dealership oil change experience at my local North NJ Chevy shop yesterday. But it was jarring not seeing a single new car in inventory. Not one!
Might be a local dealer issue. Cash crunch, low on the list for receiving cars from GM, failed to place orders in a timely fashion, etc. No way to know unless you are in the business itself. Some people just wait too late to order things and miss out. Think about the ammunition shortage, heck, any shortage. Some people are still getting things because they are faster, pay more, or accept lower quality.
We have no shortages of any kind that I have seen or experienced around here. We might be the exception, but if we are, I would be very surprised.
