Uhh yeah.. that S60 interior is PURE SHOW. The interior that comes on the models that they actually sell is lame. You didn't show the front console and the dash - flat and uninspiring.
As for when does the interior MATTER? Hmm... let's take last Saturday night as an example. I took a girl out to a club in my TL. She was so floored by the sheer style of my car... well... I'm gonna make sure we go out again soon.
Your taste in cars reflects on you. I suppose if you're a neutered pet husband, it doesn't matter as long as the car runs cheap (TL, rated by Edmunds to be lowest cost-to-own in it's class) but regardless of if some of you don't see personality in this car - women perceive the very masculine styling of this car. Put it all together.
