Sequential tail lights is just another uneeded toy which would have made the new 2005 GT more expensive. I'm sure that you will be able to get it as an aftermarket item after the vehicle is manufactured. I know that you can get them for the current 99-04 Mustang GT's and V6's.
Yeah, but I don't like paying extra money for toys like sequential tail lights. That's stupid. Plus, I am a Jew when it comes to spending money. I like being cheap. That's why I currently own 2 Mustang vehicles.
I'd rather add it in later this way not everyone will have it and it'll actually be pretty neat.
In my 2000 GT I installed it the week I purchased the car and people kept telling me that my car did it! Hehe I was like "I know. I installed it myself." They loved it....
now if all the Stangs had it...then it would be normal...aka "un-neat".
Sequential taillights seem cool if you are the only person who has them. The second everyone has them the look kind of silly and there is nothing special about them. I would rather have LED taillights even though they cost significantly more.
