6: HHR SS Panel Van
If you remember anything about the 2000s, then you remember the retro car boom. Where automakers were bringing retro car models onto the market that were influenced by the past. Volkswagen started the trend with the Beetle, and one of the last retro-themed cars was the HHR. This panel van was mocked for being a rip-off of the Chrysler PT Cruiser, and not only that, but it was also a rip-off that was far too late. The HHR SS Panel Van is rare and had no real point (via Motor Biscuit).
This car has recently ballooned in interest, as these unique cars were the last of pre-bankruptcy GM. But the car didn’t offer much in the way of performance or value. The HHR was lampooned for being a pale imitation of the already existing PT Cruiser. There were better cars in this segment for the price. Not to mention the fact that the HHR SS Panel was not the most reliable car, with the repair costs averaging more than other compact cars in this segment.
