I had a rough time with my previous car. I had poured money into it, and it still had a bunch of issues. Eventually I sold it and came across this online. I loved the way they looked, and it was pretty much what I wanted.

If this counts, I have swapped the OEM halogen tag lights with some nice, bright LEDs. It gives the car a nice blueish-white glow at night.
Because it's the Special Edition, it came with the Rockford Fosgate system from the factory. I have since replaced the factory head unit with a Kenwood KDC-BT568U. High-quality bluetooth, rear USB and Aux, 4 RCA outputs, the works.
