Well, good advice, Gene, no doubt. However, after sleeping on it, the fever has abated a bit and I'm leaning against.
I did communicate with the dealer, and as far as I can tell, they were being pretty honest. They said they got it from Kia Leasing right after turn-in, and they pointed out a bit of wear on the steering wheel leather and said that was the only visible wear anywhere, which the pix seem to bear out. I asked about the credit card key, and they said it was still present and working--I think that indicates that good care was taken of the car. Apparently the tires are good, and I pulled the AutoCheck, and it shows a lot of regular maintenance. So overall, I do think it's the very best >100,000 mi. vehicle I ever saw.
On the other hand, it is gray, which I don't much care for, and my gut just misgave me on the mileage. Even if the driveline is solid, which it may well be, I worried about the smaller systems like those fancy swiveling headlights. Looking over some of the old posts here, I see that stuff is not cheap. So, I chickened out...er, made a judicious assessment of the risk/reward ratio of the business proposal.
Also, as you point out, mdude, I really want a newer example. I remember other cases where I bought something I didn't exactly want because it was a good deal, and I never really liked those cars afterwards. So onward and upward!
(Unless I change my mind. And my mind surprises me sometimes!)
