First off, welcome to the site! Second, when customizing you ride it is what you want more. Would you prefer a slumpin' system over a intake? Or a t.v. over tint? Or rims over paint? It is all about where you want to start. I usually start with the electronics in my rides. Then onto the rims and paint. But I'm not really the "performance" type in these type of cars because they are classy, not Ricers!
