Before I had a 911, I had a Honda ST1100 motorcycle. I really liked the red paint, but the Honda stickers didn't do much for me. So, I put PORSCHE stickers on instead.
What a hoot. Everybody (except other ST1000 owners) thought it was the real deal. Only one guy was sharp enough to ask, "Well, if this is a Porsche motorcycle, why does it have a Honda "H" on the oil filler cap?"
