Should I buy 2 Blazers?

[70Chevy4x4Nut]

Just a quick question. I'm looking at 2 blazers, one is a 72 4x4 and the other is around a 79 2wd. The 72 is shot bodywise but I wanted it for parts. The 79 has rust as well and a bad transmission. Neither one has a title. He wants $500 for both, but I just offered to buy the 72 for $250. He refused the deal. Is there any worth to the 2wd without a title so I can recover my money back. I guess he might still take the deal for the two. I assume the 2wd blazers are kinda rare, so maybe the frame might be worth something. But without a title, I'm not sure.

thanks
