Republican candidate John McCain drives a Cadillac CTS, according to Car and Driver. The 2009 model tops out at an MSRP of $38,980. McCain’s payment for this auto loan would be $813 a month with 20% down and a 6.5% interest rate over 48 months. That’s not as crazy as most of the celebrities featured here. But isn’t it odd that he doesn’t drive a more fuel-efficient vehicle?
