Wayne / Pappy,
I wouldn't be overly concerned about a repaint or about door jambs that don't line up. I have a hellacious gap top-to-bottom on my doors. I've been told it's simply old door hinges or springs, which are supposed to be easily replaceable. I've never bothered. If you are concerned about the doors, sit in the car with the doors closed and see if the windows go up and down within the seals. If the windows mesh with the seals, then you are OK. If it's a little bit off, that's nothing too major either as the window likely needs to be reindexed. This also isn't uncommon if they've had the seals replaced on doors and around the A-pillars, T-Tops.
Short of any frame damage/rust or major leakage from any components, the car seems pretty good for the price. At the price they are asking, you aren't going to get an EXCELLENT-rated car, nor an all original.
I personally don't care if a car is "numbers matching". Take a look at my car! :L I say "numbers matching" is for people that plan on having a garage-queen, a judged car, or plan on selling the car for a potential profit (which nowadays is a very risky bet.) I'd rather have a healthy running car that's mechanically solid than a numbers matching car that has more than it's fair share of problems. I can tell you with absolutely no hesitation that I'd take my car over a mint condition 'matching numbers' 1980 anyday!
If you'd give the car a 3 out of 5 stars, then I think it's a pretty good deal.
