I have a 2000 Buick Century. I know it'* not a cool car but I was wondering if anyone had any ideas for me that didn't cost a lot of money. everything I do is just for fun pretty much. So far i have painted my own racing stripes on it and painted the rims the same color. I have a spoiler that i will be painting the same color and be putting on my car. i got the spoiler for free and I was also given the car for free. So I haven't really put any money into it. The car is not in the best shape. It has almost 300000km on it and has rust in the usual places. So if anyone has any cool/funny ideas for my car, I would like to hear them.

Welcome to the forums Cameron!
When I was younger, I did some fairly crazy stuff to some of my cars, and I know many went huh..what the heck are you thinking! Oh man those were the days of personalization!
I think some of the guys in high school went onto workin body shops!
So you are not going to hear me put down guys trying different stuff to their cars, it'* all in good fun and a learning experience!
Sure I could recommend fog lights in the lower front spoiler, de- badging, pin striping a narrower set of stripes etc..but it'* not my car, and I really want you to take a step back while looking at your ride, & make the decisions of what you think the car could use, or eventually look like!
The spoiler sounds great and fit and finishing details are all about your own personalization.
I know when I was looking for ideas, I would look at similar cars and see what others had done to them. Larger tires, rims, lowering, anything is possible, but often stuff cost too much and keeping it simple and just driving it a bit personalized is more fun in the end anyways.

Thank you for the welcome and the new ideas.
