I've got a 2013 Ford Focus Titanium 5-speed in Performance Blue. Covered in hail dings from day one, but that's okay, cause I got it for over $8000 off.
I haven't done much to it, as I can't justify spending any serious money on it yet, but I do have an open-ended air filter that makes a very nice sound Also, I've done some tasteful Plastidip on the wheels and the trim and installed a pair of yellow Lamin-X fog light covers (in progress shot below). Someday I'd like to put a catback exhaust system on it, but that's it; the suspension is already a great balance of handling and comfort, and any lower would be a huge liability on the potholes of New Orleans
Sorry for the bad picture, it's the only one I have on my phone!!
