skip spending a thousand dollars on all that underglow bullshit, sell your asscart, and buy a real car.
i have some respect for tuners who ACTUALLY tune their 4cyls, one of them is a good friend of mine, and he doesnt put gigantic wings and body kits and all that shit on his car.
the only really visible mod is the hood latches, which he says he actually needs, but w/e. he also has a V8 malibu (and he's having me weld parts on another honda

)
i have a 4cylinder myself and i dont really need the extra horsepower that i COULD have, but dont bother with.
in short, your neon lights are superficial.
