Hi Forumers,I am driving a E46 325 year 2001. This car comes stock standard with out a reverse sensor. I am planning to upgrade to one with a sensor and seek your recomendations. 1. should i change the bumper and get one with a reverse sensor from the chop shop? An one of you seen where i can get this?or 2. Buy a reverse sensor module from the chop shop and fix itor 3. buy a reverse sensor module from a accessory shop and fix, but this is ugly as it will not be flushed with the bumper and does not lok original.Plse advise as I am passing this car to my wife and the last thing i want is she whcking into something while reversing!Appreciate your thoughts / comments.Cheers!
