69 c10 a good purchase?

[69c10kc]

I have the opportunity to purchase a 69 shortbed non-stepside c10 from somebody that restored it and lost interest. It had a frame off restoration about 7 years ago and was restored to original. it has a 350 w/ factory A/C and tach. It has been sitting in his driveway for the last 3-4 years not moving. He wants $4000. Do you think that this is a good purchase? I would like to get it back to respectable shape. Is this a good investment? Any comments would be appreciated. Thanks
