I have had Ravelco on my 2002 civic si since I bought it in 2005. No thefts or attempts, but that doesn't mean it works. I know people who swear by it as the only reliable anti-theft device, but it seems under the radar to me. Thoughts?

 

most new cars have chips in the key that won't allow the ecu to start the car without it,similar to that thing. the only problem is most cars like this are stolen via tow truck or flat bed. the only thing worth investing in would be Lojack or something similar.
