I have a buddy that's had a couple of Porsches (GTS and Turbo S) who doesn't like to valet because of some of the reasons on this thread. He texted me once saying he was going to meet some friends at a club and decided to take the Porsche and valet it. When he got there, the wind was let out of his sails when he saw some Ferrari's, Lambos, and McLarens parked out front.
But yeah, I'm not big on valeting but will do it occasionally if it's going to be a lot easier. Last time I was at Pappas Steakhouse, I drove through the lot to self park, but there was nothing. Instead of acting like I was back in college and parking at the end of an aisle waiting for a spot to open, we just went to the valet and walked in.
