This $126,000 Buick reveals the next big trend in classic cars

The next big thing? The '80s.

Kids from that era are now adults entering the car market, Craig Jackson, chairman and CEO of the Barrett-Jackson auction house, told Business Insider.

And now that they've got money to spend, they are forgoing the traditional limits of the classic car world, prefer ing instead the cars they grew up wanting.

During this year's Scottsdale auction with houses Barrett-Jackson, Gooding & Co, RM Sotheby's, and Bonhams, overall sales were down about 15%. That's a major drop after years of rapid growth.

While Ferrari road cars failed to meet expectations, cars from the '80s, long seen as out of place among automotive royalty, brought in huge prices.

A 1984 Ford Mustang GT-350 sold for $71,500, while a 1987 Buick GNX went for $126,500.
