That's the fishyest ad I've seen in a long time;
First you've got a 4 cyl Rubicon...though the vin supports it as Rubicon 6 cyl of course
Second his math is off; 56,000 miles on 35's on an odometer set up for 31's would be 64,000 actual miles
plus a ton of other wierd things if it is actually a 4 popper
