A rundown to the 'numbers guys'.

GNX #281:   

-U.S. Route 281 starts in Southern Texas near the Rio Grande and Mexican Border and ends up in North Dakota near the Canadian border.

-Route 281 runs through the center of the U.S., GNX 281 is in the middle of numbers 1 and 547

-Route 281 is approximately 1,875 miles in length, GNX 281 has 1,872 miles (close to 1,875 miles)

-GNX 281 has the same area code as Houston, TX  (281)


Buick rated it at 276 Horsepower (the magazines rated it at 300 HP), actual is much closer to 400 Horsepower

Deemed the fastest production sedan in the world.  Beat the Ferrari Testarossa, Lamborghini Countach and right beside the Porche 911 Turbo

 Also beat the Callaway Twin Turbo Corvette (375 HP), a GM oops

0-60:  4.6 seconds

1/4 mile: high 12's 

These cars have been collectors since day one and is a sound investment

They even hold up well through weak markets and look when they do in STRONG markets

Reprogrammed motor and transmission for more boost and tighter shifts

Garrett T-3 Turbo with ceramic impeller, less turbo lag, quicker spool
