Very occasionally, and I'm very selective. I mean, I like a bit of Vivaldi or Holst's planets every now and then, but not very often. My Mum's a violin teacher and I grew up with lots of it but I don't listen to it much any more. Saying that, I like a lot of ambient music, which is pretty much the modern equivalent of classical, and I love it when classical is incorporated into, say a rock track. Muse are a great example for that.
