You didn't have to grow up in the 1980s to love the Buick Grand National. It was without question one of the coolest cars built by GM during an era which didn't have many great cars, let alone icons. But the Grand National has stood the test of time. It's a classic and an icon that's now fetching increasingly high numbers at auction. But it was in 1987, the final year of production, when Buick launched the GNX, or "Grand National Experimental." Even then it had sticker price of $29,000.

Just 547 examples were built by Buick, and they were shipped off to McLaren Performance Technologies for an upgrade. Output from its turbocharged 3.8-liter V6 was upgraded from around 245 horsepower to 276-hp and 360 lb-ft of torque. 0-60 mph was clocked at 4.3 seconds, and it boasted a mid-13 second quarter mile time. All examples were painted black with a black and grey interior. And now number 85 is heading to the auction block. It has just 45 miles on the odometer and the stock interior plastic is also perfectly intact, and it even comes with the original promo jacket and window sticker. It'll be offered through the Mecum Auction later this month with no reserve.
