Kowached,
We own an autobody shop and know a little about paint on cars. The paint on the 97,,, Smoke Silver,,, is just about the most perfect paint job I have ever seen. I check all cars I buy with an Electronic Thickness Gauge for paint work and this car has never been touched. As far as the corrosion recall you mentioned, I have no knowledge of that and perhaps it was done on one of my service visits. A lot of times it is just a drain hole that is plugged and if not cleared could lead to a problem down the road.
Pete
