Definitely get one. It will make wax/sealant application easier, and in a while your 2012 won't be new anymore and it WILL need correction. You'll already have the tool to do it and might just need to add a couple pads and a polish/swirl remover to do so. The bonus is with just a wax/sealer type pad you get the chance to get used to the machine before you try to do any correction with it.
