help w/ buying a blazer

[skybluewaters85]

Hey everyone, I am a newbie. I am looking at taking the leap in to blazer ownership. In a couple days I will be going to look at a 72 k5. The owner says it has a 350 with an auto tranny. He started the restoration. He says the body is mostly rust free and most of it is in primer. There is rust in the floor, but I have no idea how bad. There is also some rust in the driver side quarter ahead of the wheel well. Help me know what to look for and pretty much let me know when to run from this potential project. he is asking $3500 and it comes with some new interior parts. Hopefully you can help me a little bit. Thanks.
