Haven't had any problems with my Graphite which just got its 36th coat of Zaino last weekend. As for body mods I like the SRT front end on the LTD, nice looking touch. I am considering doing something with the strakes, remove them and then refinish that area and maybe a set of "Cobra" look side pipes. I love that look on the old Corvettes and Cobras.
Black paint is tough to maintain. I had two black Pt's before my Crossfire and you had to really stay on them. Black is a very unforgiving color.
