To the OP: Do you live in NYC? For some reason, it is common to tip everyone you cross paths with who does not kill you in NYC. I'm just kidding...a little. But, no, I will not tip my service guy on this car or any other car I own. I will never own anything more expensive than this car and yes, I can afford a car much more expensive w/o going into debt. If someone goes above and beyond their normal job expectations, I will tip them. For example, my daughter was home from college over the holidays and her windshield on a Nissan has been really problematic and foggy during rain. We could not get it to remain clear during rain no matter what we tried. It had a film that we could not clear. I finally called Safelite to just put in a new windshield. The guy showed up early and refused to put in a new windshield. He insisted he had cleaning supplies that I could not buy that would clean her windshield. He was right and I gave him $50 for his effort. But a service guy who is just following procedure, nope, I will not tip. Even if this is a $200k GT3...especially if it cost that much. As a matter of fact, my sales rep has scored at least one additional sale because of me. He thanked me for my recommendation and that is enough for me.
