1: Favorite mod was the lasfit LEDs, easy to install and I love the switchback signal lights.
2: I would like to see some easy to install ambient light kits that sync to music, many of the after market kits require taking panels off. My second option would be leds for the cup holders.
I've been experiencing the same engine shaking on stops, and I can feel it through the brake pedal. I only see this when the temperature is below freezing, and when the engine temp is cold. I took it to the dealer, and they couldn't find anything.
