look into da light !
LED's everywhere....heads/fogs/turns/park/3rd brake light/puddles if applicable....which will help with the appearance part, as well as improve your safety too
Depending on the current color scheme of your Expy, some folks here seem obsessed with de-chroming the trim pieces for some reason, either with a plastic wrap, dip, or paint...ie window pillars, door handles, grills, name badges/lettering ect....
And yes, you can change the tires/wheels/brakes/shocks, raise or lower the suspension, but those mods are a bit more involved, because when you change the geometry, you have to maintain clearances & make adjustments for speed/rpm/handling ect....
However, there are many threads here on almost every possible mod, so do a search & have fun
