Autoquake, the online used car retailer, is promoting stocks of convertibles ahead of the anticipated seasonal demand increase in the new year.
Autoquake claims the convertible sector has seen values drop by around 10% in the last two months.
"The market for convertibles always goes quiet in winter, but this year’s price drops are steeper than normal," said Fredrik Skantze, Autoquake.com’s founder.
"Smart buyers can take advantage of this seasonal trend to buy a car for hundreds of pounds less than they might pay in spring or summer."
Autoquake stock has seen an average fall of 7.6% from September to November. While convertible prices have dropped 10%, estates have fallen by 8.3%, five-seat MPVs have dropped by 7.9%, and executive saloons have lost 6.9%.
"We expect prices to stabilise or rise slightly in January, and convertible prices will pick up in the spring," said Skantze.
