If "bang for the buck" is part of the criteria, there aren't too many items one can really list, seeing as how everything is so expensive. But if I had to pick one, it'd be clear (no amber) tail lights. I think that $160 mod goes the furthest in visual appeal while remaining quite affordable. It can make a 97 look as fresh as an 04!

(I may be bias seeing as how I am an optics-fiend.)

But if you want even MORE bang for the buck, no mod can beat RAIN-X @ $1.99!
