Around here we like to predict which cars will become future collectibles. This isn't exactly easy, and there are a lot of factors to consider when deciding whether or not a car will become a collector's item. Everyone reading this has that one friend who thinks their car is going to be collectible because it's a limited edition. While being rare certainly helps certain cars, like a one-of-three Ferrari California with a gated manual transmission, this is not always the case. So, which rare cars will never become collectibles?

Sometimes a rare color helps a car's value. BMW's Laguna Seca Blue (which we love) is a great example. M3s painted in this color are now worth thousands of dollars more compared to those in other colors. However, a rare color doesn't always result in crazy prices. The 2009 Chevy Cobalt SS was offered in Rally Yellow. Just 36 sedans got this paint, making it extremely rare. However, you won't be seeing any 2009 Rally Yellow Cobalt SS sedans selling for $50,000. In fact, they really aren't worth much more than any other Cobalt SS sedan. Sorry if you have one of these cars and are waiting for it to appreciate. We don't think this will ever happen. Like a rare color, special versions of your normal car won't be collectible either.

Special editions of cars really irritate us. Many times they are just a normal car with a few new badges, like the recent Jeep Renegade Dawn of Justice Edition. If you really liked the recent "Batman v. Superman: Dawn of Justice" movie you'll probably love this car but that doesn't make it a high-value collectible. Even when the car is more expensive, like the Audi S4 Special Edition, prices are not always guaranteed to rise. The S4 Special Edition came out in a limited run of just 250 units. Available in the US only, it had unique front and rear bumpers, a carbon fiber trunk lid spoiler and lower front splitter, a functional rear tow hook, and a high gloss painted grille with the Quattro emblem. It even had Recaro seats and a shift knob with "1 of 250" on it.

Even a rare Audi such as this doesn't bring in much more than a standard car. So this makes us wonder: What really makes a car a future collectible? Just because a car is "rare" doesn't mean that tons of people will want it in the future. Supply and demand are funny things. We suppose that the best way to judge whether a car is going to be a collectible is to see what happens when the supply of these cars in "good" condition drops. That is what has begun to happen with cars like the E30 M3 and Acura NSX. However, you may be too late on those cars (depending on your budget). Make sure you find a car with a devoted following and dwindling supply. That may be a surefire way to find a future collectible.
