I would not recommend getting a bra for any car. FIrst reason...it's so 80's. Second, bras will actually ruin your paint unless you are religious about taking it off after every rain storm and humid day to let it dry, and cleaning and waxing under the bra every week. If you get some dirt or sand under the bra, it acts like a fine sandpaper and scratches the hell out of your hood. As for the moisture, if any gets trapped under the bra and if the car sits in the sun for an extended period of time, the moisture basically cooks the paint and discolors it.
If you really want some protection against rock chips and stuff like that the 3M clear bra is very good. It costs about $500 but it will last for 4-7 years depending on how you take care of it. A lot of new car dealers are offering this as an option due to the water based paints that they are using now.
