Should have mentioned, it had a transmission rebuild about 120,000 miles ago. Has had its oil changed every 3500 miles, and valve adjustments done on schedule throughout. Engine has not been rebuilt.

He is asking $3500, which I think is high given the mileage. I was waffling between offering $2000 (he may see this as offensively low), or $2500 (which is about as high as I'd like to go on something with these miles, and I think he'd take that offer), or offering nothing and continuing to look, although it's hard to imagine finding something that looks this good at half the miles.
