All the more incredible is that the cars, VIN numbers 457991 and 457992 have never been separated, rolling off the Pontiac, Michigan assembly line in sequence in 1987, the Grand National’s final production year. No modern-day Buick, like Encore GX or Enclave, are anywhere near as cool.
And soon they’ll be up for sale, as a pair. The so-called Buick Grand National “Twinz” are set to cross the stage at Mecum Auction’s Kissimmee event next month. Both are powered by a Garrett-turbocharged and intercooled 3.8-liter V6 linked to a three-speed automatic transmission.
Other identical features include 15-inch aluminum wheels wearing Goodyear Eagle GT rubber, black exterior with two-tone black and grey interior, bodyside moldings, blackout grille, six-way power driver’s bucket seat, AM/FM/Cassette radio with upgraded Concert Sound speakers, air conditioning, tachometer, and a power antenna. Heck, even the plastic coverings over the floor mats still exist.
