This 1977 Buick LeSabre that many would view as grandpa’s cruiser surprised pretty much every bystander at the entire track. The car is based off of the LT1 platform and with the help of some nitrous is able to scoot down the track in single digit times! Perhaps our favorite part of this one is that the car maintains a full original interior and almost entirely original suspension. Check out this insane nitrous monster in the video below!!
