A couple of other updates. Questions: "Are there leaks?" Not what I would call leaks. All these cars have some seepage, but nothing I would call an actual leak. It's parked in the garage over beige carpet and there are no stains. I do see a little bit of oil on the bottom of the transmission pan, but again nothing that actually drips. I had the valve cover, rear main seal and oil pan gasket all replaced after I bought it. Shocks, ball joints, link kits, u-joints all replaced, as well. "Rust on the doors?" There's no body rust I know of anywhere. The best place for rust to show up is the underside of the doors. I'll take pictures this weekend and post. Unfortunately, yes, it's still raining in the Houston area. I took some pictures, but there's just not enough light to get good enough resolution. Should be sunny this weekend. "Are there any problems starting it?" No, it starts every time within 1-2 seconds... maybe 3 when it's been sitting longer.
There is one crack in the rear bumper filler. It was there when I got it. I never replaced it as it's just not that noticeable. It could probably even be filled.
On the dash gauges. The oil pressure gauge seems to have stuck on 80. It was working fine last week, but today not.
