I think my favorite thing I have done that could be in that price range would be the headlights. I got mine with HID's so that made then a little more expensive but without that it will be in your price range. Spoiler I would say also, but I have been putting mine off. The Lowes front lip is the cheapest coolest investment I made. It has held up through many snow storms and even when we had so much that I was plowing it with my front bumper. The only thing I would say about it is where it wraps around, just need to put screw and washer set up to push the lip out. I posted previously a while back if you want some ideas of how to do it. Also I like the stock mud flaps if you don't have or if you are running stock rims, H&R spacers are very nice to bring the rim and tire out flush with flares. I have pictures of that as well.
