On the N63TU the filler cap is way back in the corner near the firewall on the driver's side. Look at some pictures of 2012s for sale on eBay (eBay usually has the best pictures) and then look at some later models. Once you recognize the filler cap back in the corner from the pictures, you will be able to tell easily when you go look at the car. If the cap is in the back corner, you are good.

Is this N63 or N63TU?
