Joe, I guess "rust free" is a description based on the principle that says that "what you can't see is not there"... which should never be applied to rust in the first place.
I used this car as an example since I've started looking for my SL about 2 or 3 months ago and have been literaly horrified by the things I've seen. I sincerely hope that most of the cars I've been able to check on, finaly land in the hands of people that know what they will be dealing with, otherwise, the reputation of the SL as a nice, classic yet dependable driver will probably be heading down the drain.
It's just incredible to see what people list and even dare to show in person as cars with minor or no rust! I've driven more than 1500 miles combined to diferent locations to check on several cars, and I've even had people tell me things like "The car should be an 8.5 in a scale from 1 to 10"... only to get there and find that the hardtop was stuck in place, the footwells were rusted through, and so many other things gone wrong with the poor car that the 8.5 quoted by the seller made me think about the magnitude of the earthquake the car had lived through!
Anyway, I'll keep looking. There's plenty of these out there.
Thanks for your reply.
