The HAGI classic car index enjoyed growth of 3.7% in February, achieving an all time high of 241.9.
The index has risen by 2.9% in 2014 after a poor first month.
Intriguingly, growth has been strongest in marques other than the big three (Ferrari, Porsche and Mercedes-Benz). The Top-Ex Index, which covers a range of high profile manufacturers, rose by 5% to 244.6 - another all time high.
Aston Martin, Maserati, AC and McLaren are all reported to have demonstrated notable growth in the early weeks of the year.
Of the three top companies, Porsche has demonstrated the highest performance this year with growth of 2.6% last month and 3.9% this year.
Recent high profiles sales, including a new marque record for a 907 Longtail, indicate a healthy market interest.
Ferrari appears to be undergoing a correction in reaction to the runaway growth we witnessed last year, with a rise of 2.9% in February and 1.7% for 2014.
A series of high profile sales last year, including the record-breaking auction of a 1963 250 GT, sent prices soaring - with the marque closing up 62.1%.
In December last year, HAGI warned that current growth rates for the classic car sector were unsustainable.
