How to tell if you have all-in weather package
 

hello, I'm looking to buy a wide-angle side mirror for my 2017 brz with a performance package can only tell because of the big brake kit. Does anyone know how to check if the car comes with heated side mirrors so I can buy the option with heated mirrors.

Switch on the rear window defroster and check if your side mirrors heat up.

There is no weather package for this car. It depends on your trim level. Your profile says '17 limited so you have heated mirrors.
