I am receiving a new to me 03 Grand Prix SE from my father in the next month or so. This car is going to be my GFs DD so I am not planing anything crazy with it. The car has around 102k miles on it, and has been well taken care of. What should I be looking at as to common wear items? What are common power adders for these engines? The headlights and tails have some moister building up in them, so I will be replacing those in quick order. What are common projectors I should be looking at if I end up going with a HID set up on this? I hate being the asshole with HIDs ins stock headlights blinding everyone. Thanks for any input and throw me some ideas here. It will be a mild build at most, but I do want it to be done right.
