Holy ****!!! It's a $100 option when you get the automatic, but you get to pay $500 if you got a manual and want to add it. Again....HOLY ****!!!! I really wanted to add a spare, too. But not for $500.however, the total for all the parts (not including the tire itself, which isn't a 'GM' item) will be over $500!!! Gack!!!
Come to think of it, that's almost the upcharge to get the entire automatic transmission option, isnt' it? Anyone with an auto want to trade? It'll help offset the extra weight you have from the auto. Elbow elbow, nudge, nudge.
