Thanks guys, and yeah, the tires on these rims are about 5-6 years old, still old I guess, but not terrible IMO and they were always indoors - rubber still soft, no cracks, etc. Good enough for me.
Original Paint believe it or not. Just frequently polishing/waxing and keeping it clean. It did spend about 12 years parking outside (1996-2008). It's a single stage paint, no clear, and has been very durable. I think the car pre-dates the troublesome water based paints that GM started using a year or two later.
