First contested in 1958, the Buick Open is currently still played on the same golf course where it made its debut, and resulted in Billy Casper winning that inaugural event. Warwick Hills Golf & Country Club in Grand Blanc, Michigan was the original site, and has hosted all but one of the official PGA Tour events here ever since.
The Buick Open was actually dropped off the PGA Tour calendar for a few years in the early to mid-1970s, but regained its official PGA Tour status in 1977. For several years the Buick Open was not considered an official tournament, and two Michigan courses were the sites in those years; Flint Elks Country Club in Flint, and Benton Harbor Elks Country Club in Benton Harbor.
As previously noted, the Buick Open was not always an official PGA Tour tournament. No tournament was played in 1970-71. The tournament did return in 1972, but was not officially part of the PGA Tour from 1972-76. Returning to the PGA Tour schedule in 1977, the Buick Open has been part of the Tour ever since.
In 2009, Tiger Woods struggled with his putting during a disappointing opening round of 71, but soared up the leader's board with a 63 in the second round, before posting scores of 65 and 69 on the weekend to beat Roland Thatcher, Greg Chalmers and John Senden by three strokes.
In the first round of the 1987 Buick Open, Dewey Arnette tied the PGA record for most consecutive birdies with eight in a row, but unfortunately for Arnette, Robert Wrenn was on his way to victory; setting the 72-hole tournament scoring record with a 262.
