I do, in fact a few. Yesterday I spent an hour and a half installing rear back-up sensors in my daughter's Civic, I'm frankly surprised at how well they work for $30 from Amazon. Sprayed them with some matching DupliColor before the install. I wish I had done this to my son's Corolla before he backed it into a brick wall that was too short for him to see a couple of years back.
I know none of you guys will be doing this anytime soon on your P-Cars but figured I'd share, it was a fun and cheap project that could potentially save some teenage tears. My daughter knows exactly how to play me......
