It seems like a PGA calendar isn’t complete without a Buick-sponsored event being mixed somewhere in there. But after everything that’s happened in the auto industry, the fifty-year partnership between Buick and the PGA has now reached the final hole.

For the longest time, Buick has been an institution in the US pro golf circuit, having sponsored a plethora of golf tournaments – including two big PGA events, the Buick Open and the Buick Invitational – over the years. The car brand’s latest tournament – and apparently, last one too – occurred barely a week ago when Tiger Woods bagged his fourth Buick Open title.

Details regarding the amicable split have been kept under wraps but if you’re one to read between the lines, it seems that GM’s current restricting may have had something to do with it.

GM’s restructuring has long been an open secret, especially considering that the company was dangerously close to being shelved altogether. Now that their slowly getting back on their feet, GM is hard at work in re-establishing their brands to once again become the major players they once were.

Continued after the jump.

While a return to the golf circuit seems out of the question in the impending future, both Buick and the PGA aren’t exactly closing their doors on a reunion down the road. As they said in a joint statement: “While this is disappointing news, both the PGA Tour and Buick remain in discussions regarding future sponsorship possibilities."

For now, it’s a matter of setting their priorities straight and it looks like neither one of them considers the other as a top priority – for now.
