GAINESVILLE, Ga. -

The word on the streets in the specialty markets: expensive.

Prices for collectible cars continue to soar at a surprising pace, with zeroes being added to already expensive price tags right and left.

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

In the most recent Black Book Market Insights report, analysts shared that prices for collectible sports cars rose by 8.24 percent from April to June. Next up were exotic cars, which saw prices rise by 3.23 percent, followed by pony cars with a 1.30-percent spike.

From April to June, classic truck prices rose by 1.1 percent, muscle cars saw a 0.40-percent increase and American classic prices went up by 0.39 percent.

But these price increases aren’t holding buyers back. At a recent Mecum auction, the company sold 916 out of 1,404 vehicles for sale for a grand total of $42.9 million. The sale focused primarily on muscle cars.

Black Book also pointed out RM Sotheby’s most recent collectible car sale sold 34 out of 39 vehicles, for just under $30 million. Black Book analysts said this sale was defined by a wide selection of modern era supercars.

 “Although you really couldn’t imagine two more dissimilar auction experiences, the success of both shows just how broad the appeal of collectible cars, both vintage and modern, continues to be,” the report stated.

And the sales featured an array of notable sales, based on impressive price tags.

For example, Mecum sold a 1967 Shelby Cobra for $1 million and a 1969 Ford Mustang Boss for $465,000.

Over at RM Sotheby’s, the company sold a 1963 Ferrari 250 GT Lusso for $2.2 million and let go of a 1985 Ferrari 288 GTO for just over $2 million, as well.
