The Collector Car Price indices have been put together by a combination of classic car expertise and financial experience.
Data in our indices is taken from some 400,000 constantly growing auction results from over 16 years of sales. Each index has been put together to represent common segments of the classic car market.
Each index has a quarterly average of the sector cars' moving averages, indexed back to 2004 = 100. Where there have been no sales of a car in a month, the car's previous month's average will be shown.
