In 1987, the last year of the Grand National, Buick decided to give its mid-sized V6 muscle car some love by sending it to the folks over at ASC Mclaren. The result was the Grand National GNX, a car that seemingly decimated the competition during the late 1980’s. ASC Mclaren added larger 16-inch wheels, mild-fender flares and forward vents. The 3.8-liter turbocharged v6 was also bumped to 276 hp and 380 lb-ft of torque, numbers that are thought to be seriously underrated. The one you are viewing is located in Dundalk, Maryland, has 64,273 miles on the clock and is in beautiful condition. It is also #234 of only 547 produced, however this one has gone through a high quality repaint. The owner is asking for a “Buy it Now” price of $39,000.00, which is not way out of the ballpark for these cars. The value of these cars has been climbing steadily in recent years, so if you’re in the market for one of these bad-ass Buicks, you may want to email the seller and start asking questions.
