Here are the mods I've done so far:
Completely debadged the car, added a Scangauge II, upper stoplight flasher, cargo area LED light, Wolo horn, Homelink, cargo nets, Rola organizer, satellite radio, phone holder/charger, K&N air filter, Genius 15" black wheels, OEM 175/55R15 in front + Goodyear Eagle GT-HR 195/50R15 on rear, Polk db651 in doors, installed the OEM sub & tweeters, MOPAR stubby antenna, many coats of Klasse Sealant Glaze, RainX, window tint, fun lettering.
The Polk speakers combined with the OEM sub and tweeters made a tremendous improvement in the sound system. The wider tires have really helped the ride and handling. Everything else added to the fun factor of the car!
To be done -- paint the headlight reflectors!
