I'm guessing most folks' Tours, et al, don't have any rust problems. Mine is the same, very good shape, considering it's age.
I'm still in the middle of doing a clutch and a variety of other 178K mi. maintenance.
I found a rust spot, and it's in a difficult location. It's top of the right strut tower, backside, under the junction for the computer. I'll take a better look tomorrow and try to get a pic up.
