Just some food for thought. Why does a $25,000 Chevy Impala come with a spare tire, when a $73,000 Cadillac XTS Vsport doesn't? (let's face it, it's basically the same Epsilon II car). GM, in their infinite wisdom, sees fit to charge an extra $350 for the compact spare. We, as Cadillac owners, are either stupid, or at least GM thinks we are.
