Hey in the past 2 weeks i have been researching what mods i want to pay for. I have 600 dollars to work with. I did read " Safely Modding Your 3800" and found it helpful. But i would like mixed opinions with what to buy first up to my 600 dollar budget. My 2000 grand prix GTP is stock. Also since i bought the car last summer it feels like it has become very sluggish. Once again i had read " Safely Modding your 3800" so please dont refer me there. Thanks , hope you can all help.
