Have fun but don't do any mods that aren't easily removed in case you need a warranty claim. I.e. 5" Lift, bigger tires, etc.

'06 and up X's seem to have less issues with the Rear Diff, but it takes a while before people get sufficient mileage to have a breakdown.

My rear went at about 24K Miles, but didn't blow until the Dealer test drove it. All Warranty.
