The value of the HAGI classic car index rocketed to an all time high at the close of 2013 - achieving an increase of 7.8% in December to finish 46.7% up for the year.
Ferrari achieved impressive results in 2013, growing 7.8% in December and 62.1% for the year - a result of some big sales late in 2013, including the $52.2m classic car world record set by the private sale of a 250 GTO in October.
It should be noted that the returns generated last year mirror those set before the bubble burst in the 1980s.
HAGI urges caution, stating that "current growth rates are unsustainable long-term". However, a number of major sales are set to take place later this month, including a Ferrari 212 Export Berlinetta and Schumacher's F300.
It is likely, therefore, that the market will continue to grow further into the new year.
Other marques on the index achieved significant growth, with Porsche enjoying a 24.4% increase - up 3.5 % in December, while Mercedes-Benz was up 4.4% last month and 26.9% for the year.
