Cadillac Cimarron
The Cimmaron isn’t a car that will make you feel like you are riding in a Bentley. Some would consider this the worst Cadillac model of all time. But the Cimarron has started to pique the interest of buyers in recent years, as it was such a controversial part of Cadillac history. The car was based on the Chevrolet Cavalier, but while the humble roots might turn you off, the interior of the Cimarron was luxurious (via The Drive).
The Cimarron also had a much more refined suspension, which added to the ride quality of the car. Just the fact that the Cimarron is not a well-known Cadillac model is enough to make heads turn when they see it. The styling of the car was in line with the rest of the Cadillac lineup at the time, and the luxurious interior is a major step up. You could turn the Cimarron into a unique classic cruiser if you want to.
