1979 Pontiac Phoenix (Worst)
Talk about rare, the Pontiac Phoenix was at one point the slowest-selling Pontiac model on the market. The car was based on the X platform and intended to be a fuel saver for the brand. But the weird styling of the car and questionable build quality caused the sales numbers to make a nosedive. Sales were so bad that the Phoenix lineup didn’t stick around. You’ll seldom see a Phoenix on the road, and if you do, the car invokes many questions by curious people (via Classic Car Database).
The Phoenix boasted many performance options, but the car still remained obscure compared to the Chevy Nova. The interior didn’t offer many upgrades, and the Pontiac dealership network was a lot smaller. You’ll still find one of these every once in a while, but the resale value is nothing compared to what a Chevy Nova from the same year will fetch.
