To buy, or not to buy...
I'd call around for an area Corvette club and ask if someone with Vette experience would go with you to look at the car.
Right now, the car is disassembled...and the owner want $2800. Consider:
Money spent in paying someone to put this together would purchase you an operating vette of the same year with $ left over.
However, IF you enjoy doing restoration projects, have the time, money and patience to complete this project, for that is what it is...I am sure it will not be a simple put it back together and you're ready to roll kind of deal...otherwise the owner would have done it. That is what happens to most project cars...the owner tears into it with visions of a beautiful car at the end, gets overwhelmed by the sheer enormity of the project and then tries to sell the whole mess.
SO, if you have little or no Corvette experience, please take someone with you who has experience and knows what to look for in a vette that's in pieces.
BTW, welcome to CAC. Lots of friendly opinions and help whenever you need a question answered. Hope to see you here regularly.
