The Dinan badge is one of the ultimate BMW modding dreams. You have to attain a certain number of "Dinan Points" in order to get this, 10 points I believe.
Getting the badge would most certainly not classify you as a "ricer" in any fashion, but ratehr gain respect from people who have a clue what it means. Also i dont think they would replace your 325 badge, rather place the DINAN badge ont he left side of your trunk lid.
It usually does NOT include labor. they generally give a number of "hours" required and charge you their rate times the hours to install for labor.
Do you have a description of what the "signature series" does to the car? where are you gettign your information?
A major reaosn people also choose Dinan is that it usually does NOT void the BMW warranty.
