I would get the stereo first, simply because I think the stock stereo system sucks. And there aren't any nice looking kits for the ludes except for the WW RS kit. I guess it's all in what you want, cruising while listening to some nice sounding music or turn some heads. In my experience, I turn heads all the time, as long as you keep it clean, my exterior is completely stock. I just think the stereo is better because you spend more time inside the car than starring at it from the outside right? But if your stereo is completely fine for you, get the kit.
