1983 Chevrolet El Camino SS Runs Great Clean Title Standard Cab Pickup 2-Door 5L

1983 Chevrolet El Camino SS Standard Cab Pickup 2-Door Additional Info:

This is a project car left to me by someone mid-project. I'll be as straightforwardas I can, but I don't know much about this car or cars in general.
The body is all good except one ding near the passenger headlight. Paint is great except inside the bed. No rust. Fenders have peeling.
Good mechanical condition. Runs great. Getting a new starter in this week- I can put you in contact with the mechanics who are doing that- they can tell you more about the condition.
I assume that the mileage is not the actual mileage- there's a two digit mileage gauge and a rebuiltengine, so guessing it rolled over.
The dash and stereo is custom-wired. There's a switch to plug in music and a lot of differentchargers and hookups- whomever workson this will need to know about electronics. The power windows aren't connected right now. I don't know if/how any of the heating and cooling is hooked up. This is probably the larger part of work-needed.
The bench seat needs a cover or new upholstery. The originalsweet gray velour fabric is totally shot. So that's a job too.
The interior door handle is half-broken off. It's very difficult to open from the inside.
So yes engine/body/tires all good... interior needs some work.
