1987 Buick Grand National STK # 934
Buick produced some powerful car throughout the years and this 1987 Buick Grand National is no different. Buick had a hot car with this 3.8L V6 SFI turbocharged engine under the hood backed up by the stock automatic transmission. This GN has all the appointments that a GN should have with the badges, floor mats, hood mat and embossed headrests. The T-tops are in great condition along with the T-top bags in the trunk. Inside is cold A/C, AM/FM/CD player, cruise control, seatbelts, tilt steering wheel, cloth interior, power door locks, power seats and power windows. To stop this performance marvel are power brakes and power steering for easy handling. Outside on the blacked out exterior are Grand National rims with center caps and radial tires. If you would like more details give us a call today at toll free (866) 542-8392 or (704) 598-2130. We also welcome visitors to our Charlotte, NC showroom every day.
BUICK - The "Grand National" & "GNX" Story Part 1 of 3
I don't like too many 80s cars, but this is my favorite BY FAR. It's the only car I allow to be included with the "brute force" muscle cars of the 60s and early 70s. I enjoyed working on them and driving them when I started as a tech at a Buick dealer in 1991, in Arlington TX. Too bad Pontiac and Olds didn't also make their own version of this the same way Buick made theirs.---Buick made a V6 from wacking 2 cylinders off their great V8, while letting the turbo and PERFECT computerized spark/fuel control "get back" the lost power of the 2 cylinders, AND retaining V6 fuel economy!--(these cars could get in the high 20s low 30s on the hwy). Since this is EXACTLY a Buick V8 with 2 cylinders wacked off, and since it is a 90 degree V (like a V8) unlike many V6s, the result is a nice even power curve that does not lack low-end. It does not have near the low-end "turbo lag" as many turbo POS's today that have to redline at 8500rpm before they make any power. In fact, in stock form these engines never need to see over 5000rpm.
