What vehicles have a 6x115 bolt pattern?

My better half's 2006 Chevrolet Uplander has 6x115 bolt pattern, and I'm having a tuff time to find some after market rims for it. The same year Cadillac SRX has the 6x115 bolt pattern too, both 17",and 18" cadillac cts-v and sts-v also have a 6x115 bolt pattern.
