What Drives Classic Car Price Growth
Several factors pushed auction prices up in 2025. Rarity, with low production numbers, limits supply and raises value. Historical significance, like racing wins or celebrity ownership, adds a premium. A Ferrari 250 GT SWB California Spider owned by James Coburn commanded high prices due to its fame. Online auctions grew 500 percent since 2020, making rare cars more accessible globally. Nostalgia also fuels demand, as collectors buy cars from their youth, increasing prices.
Costs and Risks to Know
Classic car investments have costs. Purchase prices range from 1 million to 20 million dollars for these models. Maintenance costs 1,000 to 5,000 dollars yearly, depending on condition. Insurance and storage add 5 to 6 percent of the car’s value annually, or 50,000 to 200,000 dollars for a 10 million dollar car. Risks include market dips, as seen in the 1990s, and high restoration costs, like 15,000 dollars for a rare bumper. Choosing well-documented cars from reputable auction houses like Bonhams reduces risks.

With prices rising 15 to 20 percent, these models offer financial growth and driving enjoyment.
