Not sure if they have the size for our Buicks. I bought them for my Sebring. Regular price was about $102. Advance gives 15% off if ordered on internet (you can still pick them up at your local store). This only lasts for another couple of days. Then you can pick up a rebate form directing you to this website for $30 rebate. so total is $45 savings! Smart Choice Promotions : Rebates
