The April collectible car market continued strength trends seen earlier this year, and prompted Black Book editors to cite value appreciation in this market area as “astounding.”

The collectible cars market is performing well, with exotic cars seeing the highest year-over-year change.

The exotic vehicles saw a 38.3-percent year-over-year jump in price this past month, and sports cars followed closely behind with a 26.73-percent spike.

Classic trucks jumped in price by 4.05 percent, with pony cars (3.55 percent), American classics (2.22 percent) and muscle cars (0.86 percent) rounding out the pack.

“Collectible cars continue to appreciate at an astounding pace, extending the pattern we have been seeing for the last few years. Although vintage exotics still lead the way, later model exotics and near-exotics are coming on strong,” said Eric Lawrence, director of specialty markets for Black Book.

Black Book editors also pointed out that the Ferrari 308/328s, Lamborghini Countach 5000s and early Porsche 911 turbos have all jumped in value during the last year, “as collectors who are either on a more limited budget or those looking for the ‘next big thing’ have gone on a spending spree.”

Furthering this assertion, two recent auctions in Florida — Auctions America’s Fort Lauderdale and Barrett-Jackson’s Palm Beach sales —  separately broke the $20 million mark in sales.

Notable sales from the auctions included:

• 1959 Ferrari 250 GT Coupe: $715,000 (Auctions America’s)
• 1987 Lamborghini Countach 5000 QV: $335,000 (Auctions America’s)
• 2006 Ford GT Heritage Coupe: $410,000 (Auction America’s)
• 1970 Plymouth Superbird 440-6 pack: $165,000 (Barrett-Jackson)  
• 1965 VW 21 window bus: $70,000 (Barrett-Jackson)  
• 1954 Kaiser Darrin Convertible: $165,000 (Barrett-Jackson)
