Classic cars typically have several things in common, which may lead them to become future collector cars: Rare: The fewer cars made, the more valuable they'll be. Cars with limited production runs are more likely to turn into classics. Uniqueness: Cars that got a total redesign or introduced a new feature are likely worth more. Additionally, cars that include design elements that were the first of their kind and later became popular are more likely to become classics. Cult followings: Car makes and models like the Ford Mustang, Jeep Wrangler, and Ford Bronco with a loyal fan base have a better chance of appreciating and increasing in value.
