Hi just bought my IS 250 over the weekend and I was feeling the same. My first major major purchase since I graduated college 7 years ago. Looked at hybrids and thought it was insane to spend MSRP and go on a waiting list for a ugly Prius. Decided to spend to say F it and spend the extra 10 grand for the car I always wanted. Big upgrade from a beat up 8 year old altima! Got over my cheap concerns and just finished waxing her. haha. Now I'm debating if I want to spend the extra money for a clear bra from aerotect.
