Chanced upon these cars from departed series recently in two different locations, both of which had sat on the pegs for over a year at least! It was sad to see them unloved without a home for so long.

The Chevy Vega must have been sitting even longer; released in the Vintage Racing series in 2011! About 3 years spent without an owner, waiting in a convenience store; I bought it out of sympathy.
The Tucker Torpedo had worse or better luck, I found it in a departmental store. Many places where I've been, all the Boulevard cars were wiped out. When I bought it, there was still another being left behind - I still think of it to this day...

Let me know in the comments if these were decidedly unpopular, I can't figure out why these cars never met the cashier until now.
