Should I Buy???

[mbarr101]

Hey all- new to the forum but hope to be staying awhile..

Have a chance to buy a 1987 r10 Chevy. 305 engine with 31k original miles. Picture is below. I'm not a mechanic by any means but really hope to slowly restore this truck with some help. She is completely driveable right now and everything "appears" functional. Body is is real good shape for the most part and the owner says it's from FL. Has FL license plate and inspection is expired. The bad:
-driver side door needs slammed in order to shut and is rusted out on the bottom.
-interior dashboard is old and beat up. everything will need replaced at some point.
-interior bench seat is old and busted up.
-muffler is cracked and i know i'll need a new one for inspection.

I'd love to have a go-getter like this to drive to work everyday (6 miles roundtrip). Any thoughts on the offering price of $5000??

Sounds like these are pretty simple trucks to work on if something does go bad. How's the price sound? What is a bad sign not to buy this truck?

I figure I'll ask for 4k. Thoughts and advice welcome!
