My husband and I purchased a 2005 Crossfire Coupe Limited with 18,000 miles on it in December 2009. The car looked brand new, but thankfully when I joined this forum, the first posting I saw was to check for rust....which I did...and yes, there was a little in both doors. To make a long story short, with the help of my assistant, (pictured below, and yes, he can actually walk underneath the car) and the starter kit of POR15, we repaired the rust. It actually was quite easy and it was a beautiful sunny, warm day here in West Michigan.
