I was just posting about my SIL's automatic car starter so it's warmed up in the winter. It's like her favorite little luxury. I thought it would be interesting to find out all of yours!
Mine is taking cabs. In NY that can get expensive but it's way nicer than the subway or the bus. So I treat myself. One of the reasons I worked my behind off and saved all my money is so I could take cabs when I want to! (PS, we don't own a car so we don't have all that expense to deal with.)
