Well my wife bitched about losing the cupholder with the NBT retrofit, BUT she didn't seem opposed to it completely which is good, she actually said, "sounds really cool", and considering I'd retain OEM Sirius functionality (which is all we use for music anyway) and OEM navigation and OBC retention, its starting to chip at me to do it
I'm getting my rear door rust repaired in a few weeks and then I will evaluate how long haul I am being with this car, even if another 4-5 years of ownership it might be worth it - Although the $600 Dynavin or Avant 3 is still a substantial upgrade cost but will give me maybe 75% of the satisfaction - I will post up my dash mids in a sec Prop you will be impressed with how good they look - going to get installed this weekend
