Material gets brittle over time. The back seat was in nice shape, but felt like a plastic bucket. The skins on the front faded to an orange color almost, and the cushions were crumbling at a rapid pace (Like Charlie Brown's Christmas Tree). It was definitely time.
I have not had it on the road since doing the interior. Finishing up the gauge cluster now, then it's just new tires and about done. Unfortunately, it's winter starting, so I won't be on the road until spring most likely.
