Hi Everyone, my wife and I are picking up a new Corolla ascent hatch next week want to get reverse parking sensors installed. As a result, I was just wondering what is the best option for both performance and looks. The factory option looks fine (Parkassist) installed at a toyota dealer however other options like the Mongoose MRS4 system using a licenced installer also look good. Both seem to run for around the same price, although I haven't really looked ito the cheapest options and price is not the primary concern. P.S. Any better options ?, I don't want to do it myself as I do not wan't to wear the pain if it does not look absolutely perfect. Thanks, Robert
