I love my '02 GT and have had ZERO problems out of it. It has 60k miles on it now. I say get the V8. But if you have sentimental value towards the sixxer keep it. You don't want to do something you'll regret. but also don't pass up a deal you would regret. I may have the opportunity after HS to get a 2007 GT/CS or Maybe even a 2010+. But i dont know if i will because i have a ton of sentimental value to my car. It's my first car and i have dumped a little over $2k of my own money in mods alone. Although a manual 5.0 may change my mind
, considering mine is an auto 4.6.
