Not familiar with the cars, though the 2nd one catches the eye. Wouldn't be too concerned on the clutch front. It's a weak point on the car for sure, but if it's still on the original and it feels OK and can pull up hill in 6th without revs flying, just points to the car having an easier life for me.
If you can, take someone familiar with the 350/mechanic with you to look the car over, or RAC inspection else. I didn't, and it cost me. Still, initial cost out of the way, never regretted it since!
