Great question. I also used to valet part time, right around when these came out. Off the lot, the blind spots do suck, but that was easily remedied with a couple of stick on blind spot mirrors. The wheels sit pretty close to the rear end, enough so that I have never had to worry about any tail pivot on sharp turns. It has really never been an issue for me. It also serves as my DD, and while I previously had an R32, it took me no time at all to grow into it's size.
It's a quirky vehicle with its blind spots (including the roof of the front windshield when you are sitting at some traffic lights), clam-shell doors, and thirst for gas. For me, however, it has been the perfect combination of comfort, utility, and capability. I can confidently say that it has been the best vehicle I have owned, and I am consistently surprised by its ability to overcome some sticky situations/obstacles.
I hope this helps. I know it doesn't directly answer your question, but the question posed regards a challenge that I have never had issues with in the past.
