Our vehicle valuation guide relies on auction data to calculate our ranking system. The data spans more than a decade and is compiled from auctions all over the world. It is one of the largest collections of auction values with over 367,800 values. The consantly growing data collection - when possible - is paired with the vehicles on this website. This includes matching the manufacturer, model, and body style. We also attempt to align the transmission, engine, and coachbuilder whenever possible.

We use verifiable salesroom transactions to ensure transparent, reliable, and unbiased market data.

Market Trend Reports

It is hard to determine a true indicator for market values. At auction, we have witnessed passion and pride raise the price well above its reasonable value. Heavily modified vehicles, charity vehicles, and historically important vehicles tend to sway the market in unrealistic directions as well. We have also observed Regional Fluctuations based on vehicles sold at various climates, such as 'the sun belt' and the 'snow belts.'

So how do we display market trends? By analyzing vehicles that return to auction on more than one occasion. Using the vehicle's VIN number, the vehicle's recent performance at auction is evaluated based on its prior results. Using this metric, a more realistic analysis of the market can be performed.

When possible, we also attempt to determine the reasons for the increase in the vehicle's value. For example, if the vehicle had been given a restoration, new mechanical components, or had been in celebrity ownership.

Another ingredient in analyzing our data are our classic car experts, financial experience, and statistical expertise.

Displaying Market Data

When possibly, we display yearly averages, high sales, and low sales based on the data. If there is sufficient data, we disregard a percentage of the High and Low figures to give more accurate Averages. We display averages based on 'Body Styles' and 'Engines'. We display all the data, including mechanical details, auction estimates, sales values, and at what auction the sales transpired. Our goal is to provide both a quick overview what to expect to sell or pay for a vehicle, but also all additional research by the consumer or seller.
