Some people would say you are being disrespectful to the Z by driving it in traffic and weather
That being said, I have 55K miles on my 2011 Z, and I do enjoy driving it every minute. But I'm not about to question someone else's decision to keep a garage queen Z. In fact, I'm ready to DD another car and garage the Z. I want to keep the Z clean, and I just don't have the time when it gets so dirty so fast. I'll take the Z to work whenever I feel like it, plus plenty of cruise time in the hill country on the weekends
