The 2007-2010 interiors are hilariously shitty. Rubbermaid-quality plastics in a lovely shade of gray-ish that can scratch with a fingernail, with every surface that could be touched by an arm or elbow as hard as a rock. It was quite entertaining in the early days of the JK listening to guys defend these horrific interiors by saying things like 'its a Jeep, it doesn't need to not suck inside'. Of course, if it doesn't bother you, then you're golden. To each his own.
But, if you are concerned at all with having a remotely nice interior, go for a 2011+. Otherwise you'd just be guilding a turd.
A society that puts equality before freedom will get neither. A society that puts freedom before equality will get a high degree of both.
