Same guy owned the late 10 10 car that was just on ebay. He told me this car was worse and I wasn't sure that was possible. I didn't see it when I was there. How can Florida car be rotten underneath more than a salted ohio car! I looked at a red z in Fort Meyers that was sold new in Miami 4 years ago. It was worse than my burgundy car but nothing like the silver one
It's the salty air. Ocean waters coming in from rains etc.... and we all know it rains a lot in Florida, not to mention it's extremely humid there, worse than Ohio.
Same thing happens in all your ocean bordering towns. California for instance. If you live anywhere within 100 miles of the ocean the cars are subject to salty rain water when storms move in, even the moist winds that blow in can be destructive over time. I looked at many cars in the San Fran area that had major rust issues. But if you go inland to say.....Sacramento...the cars were virtually rust free.
Another thing to consider, being Florida, as long as this car has been sitting it could have been subject to one of the many floods/hurricanes that Florida gets covering the car in salt water. I'd bet you'll find rust virtually everywhere in this car. I generally avoid buying cars in Florida and stick more inland in salt free, snow free areas.
